--- url: /config/extensions.md description: Extensions and gadgets that integrate well with Citizen --- # Extensions and gadgets ## Extension enhancements Citizen works out of the box, but these extensions unlock additional features when installed. ### [PageImages](https://www.mediawiki.org/wiki/Extension:PageImages) Bundled with MediaWiki. Adds thumbnails to command palette results. ### [TextExtracts](https://www.mediawiki.org/wiki/Extension:TextExtracts) Bundled with MediaWiki. Adds descriptions to command palette results. ```php [LocalSettings.php] $wgExtractsExtendRestSearch = true; ``` ### [ShortDescription](https://www.mediawiki.org/wiki/Extension:ShortDescription) Displays a short description under the page title and in command palette results. Takes priority over TextExtracts when set. ### [MobileFrontend](https://www.mediawiki.org/wiki/Extension:MobileFrontend) ::: warning Not recommended with Citizen as your default skin If Citizen is already your default skin, MobileFrontend is redundant — Citizen is fully responsive, so its separate mobile experience adds nothing and may conflict with Citizen's layout. ::: If your wiki uses a different default skin but you want Citizen on mobile, MobileFrontend is a fine way to do that. Set the default mobile skin to Citizen: ```php [LocalSettings.php] $wgDefaultMobileSkin = 'citizen'; ``` ### [RelatedArticles](https://www.mediawiki.org/wiki/Extension:RelatedArticles) Shows related pages in the command palette when no query is entered. To also show them at the bottom of pages: ```php [LocalSettings.php] $wgRelatedArticlesFooterAllowedSkins[] = 'citizen'; ``` ### [Semantic MediaWiki](https://www.mediawiki.org/wiki/Extension:Semantic_MediaWiki) Adds an Ask query mode to the command palette. Type `/smw:` to build structured queries with autocomplete for properties, categories, and values. Works automatically when installed. ### [TemplateStylesExtender](https://www.mediawiki.org/wiki/Extension:TemplateStylesExtender) Only needed if you use [TemplateStyles](https://www.mediawiki.org/wiki/Extension:TemplateStyles). Enables CSS variables in TemplateStyles, including Citizen's design tokens. ### [UrlShortener](https://www.mediawiki.org/wiki/Extension:UrlShortener) Adds a "Copy short URL" button to the share panel for one-click clipboard copy, plus a QR code view when `$wgUrlShortenerEnableQrCode` is enabled. See [Share](../features/share.md#short-urls-and-qr-codes) for details. ## Gadget enhancements Some on-wiki gadgets pair particularly well with Citizen. Unlike extensions, gadgets are installed wiki-side (see [Extension:Gadgets](https://www.mediawiki.org/wiki/Extension:Gadgets)) and enabled per-user from `Special:Preferences`. ### [Instant Diffs](https://www.mediawiki.org/wiki/Instant_Diffs) Opens diffs and revisions in a dialog instead of navigating away. When installed, the command palette's revision history mode (`/hist:` or `!`) opens previews above the still-mounted palette so you can dismiss the dialog and pick another revision without losing your place. ::: tip Press ← / → inside the dialog to step through adjacent revisions, or Esc to close it. Without the gadget, palette activation navigates to the revision page as usual. ::: ## Extension styles ::: tip Citizen provides custom styles for many popular extensions via [skinStyles](https://www.mediawiki.org/wiki/Manual:$wgResourceModuleSkinStyles). These apply automatically when the extension is installed. ::: ### Supported extensions * [AccountInfo](https://www.mediawiki.org/wiki/Extension:AccountInfo) * [AdvancedSearch](https://www.mediawiki.org/wiki/Extension:AdvancedSearch) * [AJAXPoll](https://www.mediawiki.org/wiki/Extension:AJAXPoll) * [ApprovedRevs](https://www.mediawiki.org/wiki/Extension:Approved_Revs) * [ArticleFeedbackv5](https://www.mediawiki.org/wiki/Extension:ArticleFeedbackv5) * [Capiunto](https://www.mediawiki.org/wiki/Extension:Capiunto) * [Cargo](https://www.mediawiki.org/wiki/Extension:Cargo) * [CategoryTree](https://www.mediawiki.org/wiki/Extension:CategoryTree) * [CentralNotice](https://www.mediawiki.org/wiki/Extension:CentralNotice) * [Cite](https://www.mediawiki.org/wiki/Extension:Cite) * [CiteThisPage](https://www.mediawiki.org/wiki/Extension:CiteThisPage) * [CleanChanges](https://www.mediawiki.org/wiki/Extension:CleanChanges) * [CodeEditor](https://www.mediawiki.org/wiki/Extension:CodeEditor) * [CodeMirror](https://www.mediawiki.org/wiki/Extension:CodeMirror) * [CommentStreams](https://www.mediawiki.org/wiki/Extension:CommentStreams) * [CookieWarning](https://www.mediawiki.org/wiki/Extension:CookieWarning) * [DataMaps](https://www.mediawiki.org/wiki/Extension:DataMaps) * [DiscussionTools](https://www.mediawiki.org/wiki/Extension:DiscussionTools) * [DismissableSiteNotice](https://www.mediawiki.org/wiki/Extension:DismissableSiteNotice) * [Echo](https://www.mediawiki.org/wiki/Extension:Echo) * [FlaggedRevs](https://www.mediawiki.org/wiki/Extension:FlaggedRevs) * [FloatingUI](https://www.mediawiki.org/wiki/Extension:FloatingUI) * [Flow (StructuredDiscussions)](https://www.mediawiki.org/wiki/Extension:StructuredDiscussions) * [Graph](https://www.mediawiki.org/wiki/Extension:Graph) * [Interwiki](https://www.mediawiki.org/wiki/Extension:Interwiki) * [Lingo](https://www.mediawiki.org/wiki/Extension:Lingo) * [MediaSearch](https://www.mediawiki.org/wiki/Extension:MediaSearch) * [MsUpload](https://www.mediawiki.org/wiki/Extension:MsUpload) * [MultimediaViewer](https://www.mediawiki.org/wiki/Extension:MultimediaViewer) * [OAuth](https://www.mediawiki.org/wiki/Extension:OAuth) * [Popups](https://www.mediawiki.org/wiki/Extension:Popups) * [PortableInfobox](https://www.mediawiki.org/wiki/Extension:PortableInfobox) * [RelatedArticles](https://www.mediawiki.org/wiki/Extension:RelatedArticles) * [ReplaceText](https://www.mediawiki.org/wiki/Extension:ReplaceText) * [RevisionSlider](https://www.mediawiki.org/wiki/Extension:RevisionSlider) * [Score](https://www.mediawiki.org/wiki/Extension:Score) * [Scribunto](https://www.mediawiki.org/wiki/Extension:Scribunto) * [SearchDigest](https://www.mediawiki.org/wiki/Extension:SearchDigest) * [Semantic MediaWiki](https://www.mediawiki.org/wiki/Extension:Semantic_MediaWiki) * [Semantic Result Formats](https://www.mediawiki.org/wiki/Extension:Semantic_Result_Formats) * [SimpleTooltip](https://www.mediawiki.org/wiki/Extension:SimpleTooltip) * [SmiteSpam](https://www.mediawiki.org/wiki/Extension:SmiteSpam) * [StructuredNavigation](https://www.mediawiki.org/wiki/Extension:StructuredNavigation) * [SyntaxHighlight](https://www.mediawiki.org/wiki/Extension:SyntaxHighlight) * [Tabber](https://www.mediawiki.org/wiki/Extension:Tabber) * [TabberNeue](https://www.mediawiki.org/wiki/Extension:TabberNeue) * [Tabs](https://www.mediawiki.org/wiki/Extension:Tabs) * [TemplateData](https://www.mediawiki.org/wiki/Extension:TemplateData) * [TimedMediaHandler](https://www.mediawiki.org/wiki/Extension:TimedMediaHandler) * [TinyMCE](https://www.mediawiki.org/wiki/Extension:TinyMCE) * [Translate](https://www.mediawiki.org/wiki/Extension:Translate) * [TwoColConflict](https://www.mediawiki.org/wiki/Extension:TwoColConflict) * [UniversalLanguageSelector](https://www.mediawiki.org/wiki/Extension:UniversalLanguageSelector) * [UploadWizard](https://www.mediawiki.org/wiki/Extension:UploadWizard) * [UserProfileV2](https://gitlab.com/telepedia/extensions/userprofilev2) * [VEForAll](https://www.mediawiki.org/wiki/Extension:VEForAll) * [VisualEditor](https://www.mediawiki.org/wiki/Extension:VisualEditor) * [Wikibase](https://www.mediawiki.org/wiki/Extension:Wikibase) * [WikiEditor](https://www.mediawiki.org/wiki/Extension:WikiEditor) * [WSSearchFront](https://www.mediawiki.org/wiki/Extension:WSSearchFront)
