Note though that AFAIK the official reason for Krita "not trying to do everything" isn't because they don't want to do everything but because most users and devs are interested in digital painting.

AFAIK they wont send anyone away if they try to add more image editing stuff outside of digital painting (consider that it even has some simple animation support which isn't really something you'd expect from a digital painting program).

There is practically nothing Krita can't do in terms of image editing but people that don't even use the software keep calling it a digital painting program.

Anyone coming from photoshop would have no trouble using Krita. It is practically a photoshop ripoff with more digital painting tools.
