About Prettier UI

Prettier Lichess is a browser extension that modifies the appearance and usability of the Lichess chess platform. It allows users to completely customize the site's color palette and to import and export their own color schemes. It is available for Chrome and Firefox and provides access to community color themes hosted on Google Drive and GitHub.

Because the extension is under constant development and Lichess itself is changing, some page elements may not be styled correctly, though the styling generally works in almost all areas.
