inspect element lets me slowly re-skin mastodon. if i don't refresh it's cool
@archaicartist try something like stylish or mystyle (extensions) maybe? i use mystyle these days but stylish has been popular for ages
@zacanger stylish has no styles for it yet
@archaicartist hey, if you find customizations that you like, you can apply user styles through extensions like Stylish.
