Personally I crop screenshots with GIMP twice a year and it's absolutely fine for that. Not sure what your problem is.

If your use-case is "crop screenshots", your competition isn't Photoshop, it's MS Paint.

There aren't many image editors that are able to crop pictures in a usable way. MS Paint for example can't do that. I wonder if the "move this rectangle" method is under patents.

Maybe you mean something different by "cropping", but drawing a rectangle followed by ctrl+c then ctrl+n is fairly quick / good enough

If there was a linux port of paint, I'd consider it. Until then, GIMP is fine.

Check out Pinta. It does basic image editing pretty well, imo.

jspaint.app has you covered

GIMP is the screenshot cropping tool, or for when you want to write a Lisp program to do a single, technically-precise thing to an image. Krita for everything else!

I'm still waiting for the Krita equivalent of Inkscape.

I use Lisp extensions all the time for things people claim GIMP can't do, like draw certain shapes.

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.

What issues do you have with Inkscape? I've used it for both (semi-)professional and personal work, and the UX is quite pleasant.

Inkscape is buggy, especially when clipping. Sometimes layers or filters aren't shown properly. Editing filters is a bit arcane.

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

It's a semi-decent SVG editor (if you ignore all the XML Editor crashes), but you can't draw in it.

sounds like exactly what ronin is for

Krita can't print.
