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.
Sorry, I don’t think it’s possible with a userstyle :(
Someone can probably do that with a userscript, but that’s completely out of scope for me.
