The way I would put it is: GIMP has features, not workflow. There are a lot of things that are possible, but not by combining the basic tools and metaphors in sensible ways: each time is more like diving into the command line options of a GNU tool, finding the exact thing, and if you really, really need to automate it, it goes in a script where it can be safely forgotten. Which is, certainly, a way of doing, but not…
Actually, the way I would put it is that GIMP is the perfect example of why companies hire UX designers. GIMP is textbook example of how software can technically have all the same features, but be insanely hard to use and utterly confusing to anyone without a guide. Compare it to Photoshop which does more or less the same things but anyone can naturally pick up and use.
>does more or less the same things
Photoshop has way more features than GIMP. GIMP has some severe basic wholes like lacking CMYK support after 25 years. I think they rather wait for printers to be obsolete than actually spend time implementing the color mode.
