It doesn’t have much to offer, the code is a mess, but I know some people would really appreciate it!
To use, just download the Stylus extension for your browser (if you don’t have it already), open the link and click “Install”.
The website also has a “Homepage” button where you can post issues if you have any or ideas on what to add.
The only way to install it on kbin PWA is if you are using the PWA through kiwi browser or firefox beta/nightly (these are the only ones that support extensions, which is needed to install it)
