The goal of this extension is to broaden the horizons of themes in chess.com as right now they are missing some very unique ones. I made this extension for myself but noticed many people having a similar gripe with chess.com so I decided to make it public.
1. Download the repo as a zip or git clone it
(zip link: https://github.com/ByroBuff/LiTheme/archive/refs/heads/main.zip)
2. Go to chrome://extensions
3. Enable developer mode in the top right
4. Click 'load unpacked'
5. Navigate to and select the extracted repo
6. You're done!
To use the tool just click the extension icon to open up the settings page and choose which board/pieces you want on chess.com. Press save and next time you open up chess.com you should see that your changes have been made.
