The only thing you cannot do with the trademarked name krita is publish rip-off, spyware-laden versions in places like eBay.

(Btw I switched to Krita and I'm never going back to Gimp. Even the things Gimp should be good at, Krita is better.)
I'm still waiting for the Krita equivalent of Inkscape.
GIMP is to Emacs as Photoshop is to Intellij. Both GIMP and Emacs are fairly lean out of the box; it is meant to be molded into what the user wants. The problem is the target audience of Emacs is much more keen on programmatically modifying their systems than the target audience of GIMP.

When I first started using Inkscape, I disliked all the dialog boxes, but I'm used to them now.
