About Extra Functionality
Extra Functionality is a directory page on lichess.org that lists community-made styles and browser extensions for adding settings and features to Lichess. Most entries are made by third parties, not by Lichess. The page also lists some non-Lichess sites for related games and tools.
Styles are custom looks installed with the Stylus extension in Chrome, Firefox or Opera. Browser extensions cover tasks such as accepting random challenges, analysing Chess.com games on Lichess, and filtering challenges. Browser support differs by item: some are listed for Chrome only, and others for Chrome and Firefox. Some features listed on the page, such as the streamer layout, are now built into Lichess.
