Good enough for now
I’ve only been using it for a bit here (can’t afford photoshop and need to edit for a work project) and the only problem I’ve found is that if you do anything to the whole image, e.g. accidentally fill it with color or make the whole thing blur, you can’t undo it. Which is really annoying because your work just…goes away. Oops. But it’s free, so there’s that.
