I once tried to use GIMP and gave up after 2 hours and got the task done in figma in 10 minutes. GIMP is a UX atrocity. The interface is a cluttered mess of meaningless panels and buttons. Worst for me is i'd spend 15 mins googling/reading how to do something, look for the corresponding buttons for 10 minutes, be unable to find them, and later discover they were on a panel that wasn't enabled by default (I didn't even know you had to enable panels; i'd assumed everything that was available was there in front of me). On macOS some panels randomly disappear behind other programs.

It was like using a computer program in your dreams where things don't really have to make sense.

My theory is this is a classic OSS problem where everyone wants to contribute their pet feature but the project lacks discipline and nobody wants to remove, organise, and improve (especially where the latter can be 10x harder and more tedious then the former). This could be an argument for opinionated leaders in OSS projects, because at least they'll say 'no' and do things 'their' way a lot of the time, which is often better than the 'anything goes' philosophy.
