"Export As" vs "Save As" ... Almost any program that can "export" to multiple formats uses "Save As" for the display. This is just one example. And while I appreciate the nuanced nature, and frankly in this case could go either way. When you combine all the options/features Gimp is by far the hardest image ui I've used.
My favorite was probably PaintShop Pro before 10, and second is probably Paint.Net (if it had a few more features). A simple, easy to use interface with the majority of features really accessible. Gimp offers so much more, though frankly, it's about 10x as hard to use. I only do so when I want to do something that's difficult in Paint.Net or Krita.
I want to like it, I want to use it... that said, If you had a few users who like other software use it, nobody I know would choose Gimp over other tools as a preference. I don't always like changes that are made to an application I've used for a while, and can understand resistance from Gimp developers and users. It doesn't matter, sometimes convention should win, sometimes making things easier means change, and sometimes making things consistent means an inferior technical choice.
