My phone’s pixel art wallpaper was made in photoshop (turns out that’s a really bad program for pixel art)

looks puzzled

What functionality would you want that Photoshop lacks? I’d think that everything that one could want is in the “heavyweight” image editing programs. You’ve got user-specified palettes and color reduction to same. A single-pixel tool, flood fill, zoom, rectangular fill, layers. Maybe someone could have some kind of functionality to help with isometric stuff, dunno if it has that, but your image isn’t isometric.

thinks

Maybe multiple views of the same image concurrently at different zoom levels?

No, it can apparently do that these days. Looks like GIMP can too.

Maybe showing a grid, especially at high zooms? I’m pretty sure that it can do that.

Yeah:

And GIMP can too:

I can imagine that maybe for sprite animation, there’s stuff that could be added, but I don’t think that that’s what you’re talking about.
