first thing that pops is a phrase of some biologist regards why evolution made plants green and not blue (physically, blue can absorb way more energy from the sun)... SPOILER: because makes the plantae organisms way more stable rather than performant (which opens up less windows for failings regards evolution). i use Gimp for digital collages, dead simple pixel-art and even composing a poem book for my beloved one! and that tool if it isn't perfect for the job, is probably about adjusting expectations ¶ why society can't re-signify a offensive word?
we have Krita (i never used) too... Gimp with its core open (viva the GNU license)... who knows how a bunch of hackers doing stuff for free feel when some fancy hipster smelling proprietary apple juice appears suggesting UX re-write (just in case i didn't even read the blog) based on what the rotten industry ⟨most of the time, rot⟩ wants! --cheers to a more slow paced and thoughtful world, by the way
i think pie-menus also should add a keyboard navigation. for me they are more than just controlling stuff with the pointer (interesting mailing list read about what Apple came after a research around 30 million of USD on UX: https://www.asktog.com/TOI/toi06KeyboardVMouse1.html ※ SPOILER: the mouse wins), but, again, for me radial-menus are much more than using the pointer but rather a sweet visualization, too.
different keys on hold for different functions when selecting a pie-menu direction etc. the sky isn't the limit anymore - also some thoughtful consideration where the mouse should be transported (if at all) when opening certain menus?
