Opera Nalakuvara, customized Taiwanese browser — Part 3: Third party components and menus

By Jedi Lin

Introduction

In the previous parts in the series, we discussed initial planning and customizing the installation procedure, and tweaking Opera's default settings. This is great, and these parts of the procedure have already provided a great number of useful customizations.

But there are some things Opera can't do by itself. As mentioned in the Guidelines section in Part 1, we have no choice but to use third party components to achieve some functions. The components I used within Nalakuvara are as follows:

• User CSS (user stylesheets): Put in OPERA_INSTALL_PATH\styles\user\ by default
• User JavaScript (UserJS): Disabled by default
• Plug-Ins: Put in OPERA_INSTALL_PATH\program\plugins\ by default
• Java Applet: Requires Java Runtime Environment

In this article, I will show how these components were used in Nalakuvara. The contents are as follows:

• User CSS
• User JavaScript
  • Adblock Plus
  • Autosizer 2
  • Customize Google
  • HanConvert
  • HTML Ruby
  • Open in Background With Long Press
  • Textarea Backup
• Plugins
• Java Applets
• Altering menus and toolbars
  • Dictionary and translation features
  • A note on encoding

User CSS

Opera has already achieved some leading support CSS-related features, such as Fit to Width, and support for all the CSS3 selectors. Opera@USB includes some handy advertisement blocking functions purely via CSS.

User CSS can be enabled and disabled on demand via the Opera View menu, or through adding a button to do it into your toolbars. Adding custom buttons to enable/disable user CSS however is quite difficult. Opera's internal command "Select user CSS file" targets a particular CSS file by its order in the User CSS path. In order to make custom buttons that apply User CSS on, we have to manipulate the CSS file order in the path.

On Windows, files are arranged by filename. In Nalakuvara I have taken CSS files from Opera@USB and renamed them with low numbers at the start (eg 000_Antiflash.css and 000_bantiad.css) to make sure they are the first two files. On Linux or FreeBSD, however, it doesn't work that way, so sadly these buttons work only on Windows. I will talk about these buttons later, in the "Altering Menus and Toolbars" section.

My 000_Antiflash.css stylesheet blocks all Flash content in a web page:

@charset "UTF-8";
/*
Name: Flash Blocker
Version: 1 08.2005
Beschreibung: Flash und Shockwave Blocker Version 12.06
*/

object[classid="clsid:D27CDB6E-aE6D-11cf-96B8-444553540000"],
object[classid="clsid:166B1BCA-3F9C-11CF-8075-444553540000"],
object[type="application/x-shockwave-flash"],
embed[type="application/x-shockwave-flash"],
embed[type="application/x-director"],
embed[quality]
embed[src$=".swf"]
{display: none !important;}

000_bantiad.css blocks particular image sizes from appearing on a web page:

@charset "UTF-8";
/*
Name: Grafik Blocker
Version: 1
Beschreibung: Grafik Blocker
*/

[height="60"][width="468"], [height="60px"][width="468px"],
[height="31"][width="88"], [height="31px"][width="88px"],
[height="336"][width="280"], [height="336px"][width="280px"],
[height="300"][width="250"], [height="300px"][width="250px"],
[height="250"][width="250"], [height="250px"][width="250px"],
[height="400"][width="240"], [height="400px"][width="240px"],
[height="120"][width="240"], [height="120px"][width="240px"],
[height="60"][width="234"], [height="60px"][width="234px"],
[height="150"][width="180"], [height="150px"][width="180px"],
[height="600"][width="160"], [height="600px"][width="160px"],
[height="125"][width="125"], [height="125px"][width="125px"],
[height="600"][width="120"], [height="600px"][width="120px"],
[height="90"][width="120"], [height="90px"][width="120px"],
[height="60"][width="120"], [height="60px"][width="120px"]
{display: none !important;}

This is an excellent demonstration of CSS attribution selectors.

User JavaScript

If you are customizing the Opera 10.50 Labs pre-alpha snapshot, you will find that the JavaScript is a bit unstable in part. Unfortunately this means that several of the Nalakuvara User JavaScript additions will not work. This will be fixed in later 10.5 releases.

User JavaScript allows us to add much more functionality, although because of compatibility and security concerns it is disabled by default. To enable the User JavaScript feature, you need to tweak the following preferences:

For example, the OPERA_INSTALL_PATH\custom\defaults\operaprefs.ini file on Windows should look like so:

Opera Preferences version 2.1
; Do not edit this file while Opera is running
; This file is stored in UTF-8 encoding

[User Prefs]
Enable Gesture=1
Enable Drag=255
Doubleclick to Close Tab=1
New Window=1
Open New Window in Background=1
Show panel toggle=1
User JavaScript=1
Always Load User JavaScript=1
User JavaScript on HTTPS=0
User JavaScript File=userjs

[Fonts]
Menu=12,4,0,0,0,0,新細明體
Toolbar=12,4,0,0,0,0,新細明體
Dialog=12,4,0,0,0,0,新細明體
Panel=12,4,0,0,0,0,新細明體
Tooltip=12,4,0,0,0,0,新細明體

[Network]
HTTP Accept Language=zh-tw,en;q=0.9
Check Local HostName=0
Enable HostName Expansion=0
Enable HostName Web Lookup=1
HostName Web Lookup Address=http://www.google.com/search?q=%s&sourceid=opera&num=%i&ie=utf-8&oe=utf-8

User JavaScript on HTTPS remains disabled for security concerns. If you have to enable this preference, please, think about it carefully, and warn users too.

User JavaScript File can be an absolute or relative path. It is wise to let users choose where to put their own user JavaScript files, However it is convenient to predefine a relative path here. The tricky part is that the working directory is different on Windows and Linux/FreeBSD. On Windows, Opera's working directory is where opera.exe is located, ie OPERA_INSTALL_PATH. On Linux and FreeBSD, Opera's working directory is user's home directory, i.e., ~. The User JavaScript File relative path is related to Opera's working directory, which means userjs is at OPERA_INSTALL_PATH\userjs\ on Windows, and ~/userjs/ on Linux or FreeBSD.

Nalakuvara chooses User JavaScript based on my guidelines carefully. Here is my final list:

• AdBlock Plus to block web elements using CSS selector.
• Autosizer 2 (URL no longer active) to resize large images
• CustomizeGoogle to customize Google services (analogous to the Firefox extension "CustomizeGoogle")
• HanConvert to convert characters between Traditional Chinese and Simplified Chinese
• HTML Ruby to expand W3C Ruby Annotation support in Opera
• Open in Background with Long Press to allow opening of links in a new tab in the background via long mouse presses
• Textarea Backup with Emulate GM functions to backup text input in <textarea> elements automatically.

Adblock Plus

The pure-JavaScript version of AdBlock Plus uses CSS attribute selectors and optional CSS3 nth-child selectors to target elements to block. All "blocker" CSS rules are stored in cookies. All AdBlock Plus functions can be accessed via Toolbar buttons (which will be discussed in the "Altering Menus and Toolbars" section) and hotkeys, which are as follows:

• Alt-Shift-B: block web elements with CSS3 nth-child selector;
• Alt-Shift-W: block web elements without CSS3 nth-child selector;
• Alt-Shift-U: revert previous blocked web elements;
• Alt-Shift-L: revert last blocked web elements;
• Alt-Shift-E: edit blocker CSS rules manually.

Autosizer 2

Autosizer 2 lets users click on large images to resize them to fit within the browser window size, and click again to restore them to their original size. It also uses cookies to store this resize setting for each image.

Customize Google

CustomizeGoogle uses a separate customizegoogle_prefs.js file to adjust its behavior. Here are the predefined options in Nalakuvara:

Nalakuvara prompts users to change these values upon installation.

HanConvert

HanConvert is not a mature solution yet — it can't translate between Traditional Chinese and Simplified Chinese yet. It can however do character-level conversion between these two languages. The next step in the future will be improving it to phrase level conversion, and later on perhaps, full translation.

HanConvert can be accessed via Toolbar buttons, which will be discussed later, in the "Altering Menus and Toolbars" section. There is also another User JavaScript file that enables language conversion automatically for all web pages; this is undesirable as it doesn't go along with Opera's clean nature.

HTML Ruby

Opera follows W3C web standards in general, although it fails on W3C Ruby annotation. HTML Ruby fills this gap via JavaScript and CSS — it comes with a separate ruby.settings.js file to adjust its behaviour:

Nalakuvara prompts users to change these values upon installation.

Open in Background with Long Press

Open in Background with Long Press is for those who do not use mouse gestures but want similar functionality, and it works only on actual <a> links. Sadly, some users reported that this User JavaScript slows down web games on Facebook. Nalakuvara highlights this issue to users before installing it, so that if the user is unhappy with this side effect, they can choose not to install the User Javacript.

Textarea Backup

Textarea Backup is a Greasemonkey User JavaScript, and therefore needs Emulate GM functions to work in Opera. There is one variable in its textareabackup.js:

Again, Nalakuvara prompts users to change these values upon installation.

Remember: If the User JavaScripts above are installed, you can enable and tweak their preferences in operaprefs.ini.

Plugin

There is only one plugin used in Nalakuvara, and it is only available on Windows: npviewinie. This provides the functionality of the "IE Tab", rendering web pages using IE's trident engine without leaving Opera, (this is analogous to the Firefox "IE Tab" extension).

The core of npviewinie is a npviewinie.dll, which was placed in OPERA_INSTALL_PATH\program\plugins\ or anywhere listed in the opera:config#UserPrefs|PluginPath preference. I then embedded an npviewinie object using an <embed> tag with an type="application/viewinie" attribute. This, too, could be performed via a Toolbar button, which will be discussed later, in the "Altering Menus and Toolbars" section. There is also a seperate Autorender.in.IE.js to load listed web pages with the npviewinie object automatically. This Autorender.in.IE.js should be in the User JavaScript path, with related preferences enabled to take effect.

npviewinie might not be usable in Windows Vista and Windows 7 due to Data Execution Prevention (DEP). The workaround is to turn DEP off with the following command line entry:

bcdedit /set nx alwaysoff

Users have to reboot their system for this to take effect. With DEP disabled, other security issues might be raised too, so this is by no means a foolproof solution. This information is revealed to users, too.

If you are customizing the Opera 10.50 Labs pre-alpha snapshot, you'll find that due to unstable JavaScript (as mentioned earlier), these npviewinie buttons will not work properly. This will be fixed in later 10.5 releases.

Java Applets

If you are customizing the Opera 10.50 Labs pre-alpha snapshot, you'll find that this doesn't work, as the build does not have Java support included.

Java Applets, on the other hand, provide a cross-platformed solution, which might be slower but works just fine. If users do not have a JRE installed beforehand, Opera can prompt them to install JRE at the first run of any Java Applet. On some platforms users have to install JRE through the system's package management system. On Ubuntu, for example, one has to install the sun-java6-bin package via the Synaptic Package Manager to make Java Applet work.

Nalakuvara uses the ZTerm Applet (URL no longer active) to handle telnet:// and ssh:// protocols, which are necessary for telnet-based BBS. There are two different ways to include this third party component into Nalakuvara: install files locally, or use the applet page provided by the ZTerm Applet project. Either way, the ZTerm Applet stores its preferences in a .ztermrc file. This file is located at %USERPROFILE% on Windows, and at ~ on Linux/FreeBSD.

The applet page provided by the ZTerm Applet project was no longer provide applet service due to policy issue. However, the ZTerm Applet files are still available. You could upload them to somewhere else to use remotely.

By default, the ZTerm Applet uses IE as an external browser on Windows, and Firefox on Linux/FreetdBtdSD. You can predefine it to Opera by editing .ztermrc:

external-browser-command::opera %u

On Linux, you can tweak ZTerm Applet more to make it look better:

external-browser-command::opera %u
font.antialias::true
font.family::AR PL UMing TW MBE
font.vertical-gap::1
locale.language::en
use-system-look-and-feel::true

On Ubuntu, again, there is 文泉驛等寬正黑 font for better look:

external-browser-command::opera %u
font.antialias::true
font.family::文泉驛等寬正黑
font.vertical-gap::1
locale.language::en
use-system-look-and-feel::true

The applet page (local or remote) can be accessed via bookmarks, bookmarklets or toolbar buttons. I prefer using toolbar buttons; we will talk about this in the next section.

Altering menus and toolbars

With 3rd party components installed, there should be a ways to conveniently access them. Toolbar buttons are one of the best practical ways. New features (buttons) could be hidden by default, preserving Opera's default UI layout; users can also remove unwanted features, and revert them back easily.

Customized Toolbar buttons are stored in the [Customize Toolbar Custom.content] section of standard_toolbar.ini:

[Customize Toolbar Custom.content]
Button0, "訂閱源料"="Go to page, "javascript:void(function (){subscriptions = [];linksList = document.getElementsByTagName('link');for ( i = 0; i < linksList.length; i++ ){ type = linksList[i].type;if ( type == 'application/rss+xml' || type == 'application/atom+xml' || type == 'application/rdf+xml' ){ subscriptions.push( { 'title':linksList[i].title, 'href':linksList[i].href } );}}if ( subscriptions.length == 0 ) return;str = '你要訂閱哪個源料？請輸入編號\n';for ( i = 0; i < subscriptions.length; i++ ){str += i + ': ' + subscriptions[i].title + '\n';}str = str.substr( 0, str.length - 1 );ret = prompt( str );if ( ret < 0 || ret >= subscriptions.length ) return;document.location.href = 'feed://' + subscriptions[ret].href;})()", 1, "以桌面軟體訂閱 feed: 協定的源料", "RSS""

All customized buttons stored here will show up in the "My buttons" toolbar. The a potential problem here is that users might install different third party components, and one standard_toolbar.ini might not be able to fit them all. During the installation/patch process, Nalakuvara copies one of sixteen predefined standard_toolbar.ini files to OPERA_INSTALL_PATH\ui\, according to the users' selection.

The modified standard_toolbar.ini is renamed to "Opera Nalakuvara Standard" to distinguish between it and the original one. What if it just doesn't show up? There is still a way forward — users could still install Nalakuvara's customized buttons from user documents, which will be discussed in Part 4 of the series.

Menus are a little tricky. Nalakuvara's guidelines state that there should be as little change as possible in menus. The only "must-have" is Opera's built-in dictionary function.

Dictionary and translation features

There seems to be a bug in the current Opera 10.50 Labs pre-alpha snapshot — the Hotclick menu does not work properly yet. This will be fixed in future 10.5 releases.

By default, the "Opera Standard" menu contains one Hotclick (right-click) search entry for Merriam-Webster Online Dictionary, one for English Wikipedia, and one set of translation functions using Yahoo! BabelFish which includes:

• English to French
• English to German
• English to Italian
• English to Portuguese
• English to Spanish
• French to English
• French to German
• French to Italian
• French to Portuguese
• French to Spanish
• German to English
• German to French
• Italian to English
• Italian to French
• Portuguese to English
• Spanish to English
• Spanish to French
• English to Japanese
• Japanese to English

These are quite useful for American/European users, however for Taiwanese users they do not help much. There are some local popular web dictionary services in Taiwan, and Yahoo! BabelFish supports Traditional Chinese to/from English too. It was better to include these feature into Nalakuvara's Hotclick searches.

The goal is to expand the "Dictionary" and "Encyclopedia" entries into submenus (original Merriam-Webster Online Dictionary and English Wikipedia), and tweak "Translate" submenu to serve the needs of Taiwanese users:

• Dictionary
  • Yahoo! Taiwan Dictionary
  • Merriam-Webster Online Dictionary
  • Taiwan National Language Composite Search
• Encyclopedia
  • Chinese Wikipedia
  • English Wikipedia
  • Japanese Wikipedia
  • Uncyclopedia
• Translate
  • English to Traditional Chinese
  • Traditional Chinese to English
  • Japanese to English
  • French to English
  • German to English
  • Italian to English
  • Portuguese to English
  • Spanish to English
  • English to Japanese
  • English to French
  • English to German
  • English to Italian
  • English to Portuguese
  • English to Spanish

This modification was achieved through three files:

• LANGUAGE_CODE.lng, which changes menu text according to the specific UI language
• search.ini, which defines actual Hotclick searches
• standard_menu.ini, which defines the actual Hotclick menu

The default searches are predefined in the search.ini file. Just like bookmarks.adr of default bookmarks, search.ini can be locale-based. This makes more sense for we can tweak the above menu just for Taiwanese users, ie, those who use Traditional Chinese as their UI language.

Let's start with the Hotclick translate submenu. The [Translate menu] section of Nalakuvara's OPERA_INSTALL_PATH\ui\standard_menu.ini is as follows:

[Translate menu]
Item, MI_IDM_SELTRANSLATE_FR_DE	= Hotclick search, 107
Item, MI_IDM_SELTRANSLATE_FR_IT	= Hotclick search, 108
--------------------1
Item, MI_IDM_SELTRANSLATE_JA_EN	= Hotclick search, 119
Item, MI_IDM_SELTRANSLATE_FR_EN	= Hotclick search, 106
Item, MI_IDM_SELTRANSLATE_DE_EN	= Hotclick search, 111
Item, MI_IDM_SELTRANSLATE_IT_EN	= Hotclick search, 113
Item, MI_IDM_SELTRANSLATE_PT_EN	= Hotclick search, 115
Item, MI_IDM_SELTRANSLATE_ES_EN	= Hotclick search, 116
--------------------2
Item, MI_IDM_SELTRANSLATE_EN_JA	= Hotclick search, 118
Item, MI_IDM_SELTRANSLATE_EN_FR	= Hotclick search, 100
Item, MI_IDM_SELTRANSLATE_EN_DE	= Hotclick search, 101
Item, MI_IDM_SELTRANSLATE_EN_IT	= Hotclick search, 102
Item, MI_IDM_SELTRANSLATE_EN_PT	= Hotclick search, 103
Item, MI_IDM_SELTRANSLATE_EN_ES	= Hotclick search, 104

OPERA_INSTALL_PATH\locale\zh-tw\zh-tw.lng is also modified, to match this change:

1208490414="英文 > 法文(F)"
1208490335="英文 > 德文(G)"
1208490515="英文 > 義大利文(I)"
1208490746="英文 > 葡萄牙文(P)"
1208490382="英文 > 西班牙文(S)"
1209820046="法文 > 英文(2)"
1209820004="英文 > 繁體中文(T)"
1209820184="繁體中文 > 英文(E)"
1206981023="德文 > 英文(3)"
1213449683="義大利文 > 英文(4)"
1221751130="葡萄牙文 > 英文(5)"
1208670062="西班牙文 > 英文(6)"
1208490529="英文 > 日文(J)"
1213952801="日文 > 英文(1)"

And OPERA_INSTALL_PATH\locale\zh-tw\search.ini is changed, to modify the actual Hotclick search:

The "Translate" sub menu works now; now it's time to expand the "Dictionary" and "Encyclopedia" entries into submenus by modifying the [Hotclick Popup Menu] section of the OPERA_INSTALL_PATH\ui\standard_menu.ini:

[Hotclick Popup Menu]
Item, MI_IDM_DOCCOPY			= Copy
Item, M_COPY_TO_NOTE			= Copy to note
Platform Win2000-Unix-Mac-QNX, Feature Voice, Item, M_HOTCLICK_MENU_ITEM_SPEAK = Speak selection
--------------------1
Item, MI_IDM_SELSEARCH				= Hotclick search, 200
Submenu, MI_IDM_SEARCH_DUMMY_PARENT, Internal Search With
Submenu, 999999999, Dictionary menu
Submenu, 999999998, Encyclopedia menu
--------------------2
Submenu, MI_IDM_SELTRANSLATE_EN_FR_PARENT, Translate menu
--------------------3
Item, M_HOTCLICK_POPUP_MENU_GOTO_URL				= Go to page, "%t"
Item, MI_IDM_SELMAIL			= Send text in mail

The Submenu command creates a submenu — since the language string numbering schema remains unknown to the public, the locale-specific submenu names are using 999999999 and 999999998 as language string numeric identifiers. We have to add these two strings in the OPERA_INSTALL_PATH\locale\zh-tw\zh-tw.lng too:

999999999="查字典(D)"
999999998="查百科(P)"

And we mustn't forget to define the actual "Dictionary" and "Encyclopedia" submenus in OPERA_INSTALL_PATH\ui\standard_menu.ini:

[Dictionary menu]
Item, MI_IDM_SELTRANSLATE_FR_PT			= Hotclick search, 109
Item, MI_IDM_SELDICTIONARY			= Hotclick search, 50
--------------------1
Item, MI_IDM_SELTRANSLATE_DE_FR			= Hotclick search, 112

[Encyclopedia menu]
Item, MI_IDM_SELTRANSLATE_FR_ES			= Hotclick search, 110
Item, MI_IDM_SELENCYCLOPED			= Hotclick search, 51
Item, MI_IDM_SELTRANSLATE_IT_FR			= Hotclick search, 114
--------------------1
Item, MI_IDM_SELTRANSLATE_ES_FR			= Hotclick search, 117

Again, the locale-specific names are also added into the OPERA_INSTALL_PATH\locale\zh-tw\zh-tw.lng:

-1539396211="韋氏英英字典(W)"
1634087069="英文維基百科(E)"
1209820415="Yahoo!奇摩字典"
1209820051="中文維基百科(Z)"
1206981060="國家語文綜合連結檢索"
1213449720="日文維基百科(J)"
1208670099="偽基百科(U)"

And the actual Hotkey searches in the OPERA_INSTALL_PATH\locale\zh-tw\search.ini:

Any search for which Search Type is not =0 will not be shown in the Search Bar, but these can be invoked using the "Hotclick search" command. The reason to use "Hotclick search" rather than "Go to page" is to specify input encoding (Encoding=foo) and/or specify GET/POST submission (Is post=0_OR_1).

Since the Hotclick menu can be locale-based, we could go further and add English, Simplified Chinese, or versions for any other UI languages. To summarise, the following table describes the language file changes made in this section of the work:

The reason to provide this functionality is that some Taiwanese users might use computers in other countries, such as America and China, and not always be able to use Opera with the Traditional Chinese UI. With the English and Simplified Chinese UI predefined, these users have an way of using the tweaked menu too.

The English (en) and Simplified Chinese (zh-cn) versions of search.ini are different from the Traditional Chinese (zh-tw) one. Most locale-specific searches are preserved during Nalakuvara's editing process.

A note on encoding

This is not over yet. Encoding is always a big problem in CJK, so Taiwanese users often switch web page encodings. Many users asked if an encoding submenu could be included in the right-click menu, so here it is:

[Document Popup Menu]

Item, MI_IDM_Prev_PM,				= Back
Item, MI_IDM_Next_PM,				= Forward
Item, M_REWIND,				= Rewind
Item, M_FAST_FORWARD,				= Fast Forward
--------------------1
Item, MI_IDM_Reload_PM,				= Reload
Submenu, MI_IDM_AUTORELOAD_TOGGLE_PARENT, Reload Menu
--------------------2
Item, M_DOCUMENT_POPUP_MENU_BOOKMARK_PAGE		= Add to bookmarks, 1
Item, MI_IDM_POPUP_ADDRESS			= Copy document address
Item, MI_IDM_SEND_URL_EMAIL		= Send document address in mail
--------------------3
Item, MI_IDM_Print				= Print document
Item, MI_IDM_Kilde				= View document source
Item, M_DOCUMENT_POPUP_MENU_VALIDATE			= Validate frame source
Submenu, M_OPEN_WITH, Open in menu
--------------------5
Include, Internal Frame
Include, Internal Document Background
--------------------7
Submenu, MI_IDM_ENCODING_AUTOMATIC_PARENT, Encoding Menu
Item, M_BLOCK_CONTENT = Content block mode on | Content block mode off
Item, M_EDIT_SITE_PREFERENCES = Edit site preferences
--------------------8
Item, MI_IDM_FULLSCREENTOGGLE			= Enter fullscreen | Leave fullscreen

Another requested feature is the ability to∓ merge notes. It is quite simple:

[Note Item Popup Menu]
Item, MI_IDM_SELMAIL       = Send text in mail
--------------------1
Item, MI_IDM_HLITEM_CUT                            = Cut
Item, MI_IDM_HLITEM_COPY                            = Copy
Item, MI_IDM_HLITEM_PASTE                            = Paste
Item, 999999997                            = Copy & Paste to note
Item, 999999996                            = Copy & Delete & Paste to note
Item, MI_IDM_HLITEM_DELETE                            = Delete
--------------------5
Item, MI_IDM_HLITEM_SELECTALL                     = Select all
--------------------6
Item, M_BOOKM_PANEL_VIEW_MENU_SORT_BY_MY_ORDER       = Sort by column, -1
Item, M_BOOKM_PANEL_VIEW_MENU_SORT_BY_NAME       = Sort by column, 0
--------------------7
Item, M_NEW_NOTE       = New note
Item, SI_NEW_FOLDER_BUTTON_TEXT       = New folder
Item, M_NEW_SEPARATOR        = New Seperator

Here I am introducing two more customized language string numeric identifiers, 999999997 and 999999996. Again, we have to add these two strings to OPERA_INSTALL_PATH\locale\zh-tw\zh-tw.lng:

; item for Nalakuvara
999999997="合併且保留"
999999996="合併"
