When I tried to use Krita a few months ago I couldn't set the white point in the levels tool. I looked it up and the tool apparently doesn't exist. That makes it awful for processing scanned artwork in my workflow.

Soooo, The GIMP.

I use Levels filter tool for that in Krita. Already non-destructive.
