Good video, very much worth watching despite the length. New UI will look something like this:
with an option for a more classic look.
Looks like an enourmous UX improvement too, and a rewrite to QT and eliminating a lot of technical debt will make development faster.
I mean, it in a very literal way the parent project of GTK, and therefore indirectly responsible for GNOME, so that kind of checks out. I use it quite often though, and you can learn it to do what you wanna do.
Hey I don't want to come off the wrong way, couple decades ago gimp was very useful to me, when I was trapped in a company that wouldn't pay a penny for any kind of software, and on the FOSS side of things choices for imaging applications were sparse at best. Gimp was a lifesaver at times.
But it always been an interface disaster. I spent decades doing UI/X alongside other development, and gimp has always been a piece of shit designed by a programmer with the toxic "what it works" mentally.
