Photoshop's UI is terrible as well (not defending GIMP). At least for digital painting. - How to set 'C' key as to open color palette? Surprisingly, you can't do it in Photoshop. - Photoshop is the only painting app that needs a completely new interface for liquifying, instead of just implementing it as a brush. - Photoshop's 3D, vector path and animation feature are all abysmal. I guess it's to push you to buy other Adobe software.
