@squirrel here's the most useful thing I've found so far on the "making your wm pretty" front
https://github.com/grassmunk/Platinum9
It's got a theme for xfce, icons, and gtk2
It won't cover everything because linux has 3 different ui toolkits which all have to be themed differently because of course it fucking does but it might be a good start?

@troubleMoney ok this is the closest I've seen to an accurate os9 theme hmm
@squirrel the most important thing missing is a gtk3 theme but someone may have come up with something that'll look decent with it
@squirrel I believe in you!
It'd be a bit easier than working with masto themes and you did a cracking job on this 'un
@troubleMoney i don't know where to begin and i'm bad at reading through big manuals without someone guiding me
@squirrel if you start with an existing theme it should give you a good framework, then just see what bit of the theme is bugging you most for not quite being right, go to the css and fix that, rinse and repeat
@troubleMoney uhh
