I'm thinking of maybe making a web extension for cohost that looks for a link to a css file in a user's sidebar info! and automatically loads it on pages where that sidebar is visible, which would (for users of the extension) let you edit whole-page styling for your profile page (and anywhere else where the sidebar is visible e.g. comment pages for your posts) rather than just the subset that cohost allows inside your posts
Is this even a good idea? I've mostly lurked here but I've always loved what people do with their itch.io game pages and bringing something similar to here would be nice
! cohost doesn't strip empty links from profile sidebars so you can hide a link that's invisible to the user there
