Tbh, at this point I would pay for paint.NET on Linux.

Pinta is interesting, but the UI is terrible. Did we really have to remove the resize handles? They're there when adding shapes, but not when manipulating pixels/selection? Half the options I need being hidden in a hamburger menu isn't great either.

Gimp is gimp. I don't need Photoshop. And I don't want a Photoshop level of a learning curve.

Krita is interesting, but it seems to be aimed at drawing. I struggled to copy the color code from an image. By default my eyes are drawn to the massive advanced color selector on the right, but it's a trap. You actually need the tiny color selector in the top bar. It shouldn't be this hard.

I need a subset of image manipulation features in my work and each tool has a different one.
