My biggest beef is the UI constantly goes through massive changes at each release. Options moved, mysterious new configs, literally it is as if you're using an entirely new piece of software every few years.

For those of you who daily drive GIMP, well you'll be up to speed quickly. For those of us that use it once a month or so, for a day, it quickly becomes exceptionally annoying.

I'm happy if the UI isn't the best. I frankly don't care what the software looks like, or if the GUI is purdy. I just want it to work, work well, and frankly that menu items don't magically disappear, get merged into other sub-menus, or that now you can suddenly close a tool, and never ever get it back without finding some obscure menu item to re-activate it.

And if you use GIMP frequently, and are about to say "But, that's easy, you just..." then you're not a casual user.

There are more casual users than you think.

(this goes right up there with devs who change config options in files from option= to Option=, and configs= to config=.

I mean, leave it alone. Forever.

"Updated config options to bring them inline with StudlyCaps" or whatever turns my day into a ragefest filled anxiety attack on upgrade.

"Changed all config names to US English from British spelling." What?! OK b112, you now have to deal.

I don't want to deal. I want to eat doritos.)

It's funny to hear that, because we get a large number of complaints that we haven't changed GIMP's interface at all from 2.10 to 3.0 and that's why we're "failing".

We try to be respectful of existing users (and again, we get lots of complaints that doing so "holds GIMP back"). If you have some examples of massive changes you've dealt with (and from what version to what version), I'm happy to look into them further.
