the UI for GIMP is so horrifically bad that I basically refuse to use it. Not like, on principal or anything, if it improves i'd be happy to give it a shot, but because every experience I've had with it has been pretty immediately negative, and finding solutions to problems I have seems more effort than its worth. I want gimp to be good, it's a mature piece of software with a lot going for it, but it also feels like its design is kind of up its own ass, in a sense? It's weird.
