I don't need any of the advanced tools, I just want a cleaner interface for the tools that already exist. The only thing I'm able to do is make header pics for my posts. The 2.x UI is really, really old now. The time for a refresh was a few years back, but I do understand the limitations of a small team. Like others have said, I'll likely run both and migrate to 3.x when it's stable. Though, I do like the idea of non-destructive editing :)
Krita has been adding photo manipulation tools faster than GIMP is fixing their UX/UI, so at this point I think Krita will be the first to become the most viable FOSS alternative to Photoshop.
