It doesn’t. But I wait something around 20 years for Gimp, all of my hope is gone. Inkscape evolved a lot, also Krita. Gimp just made babysteps in case of UI and UX and this is basically because of the outdated underlying technology as far as I know.

I am an FOSS frontend dev myself, so I hate to say this. I would love to fully switch to FOSS gfx software, but especially with Gimp, its a pain in the ass, to work with it.

Yes, but if I wait for Gimp & Co. to become an alternative, I will be long retired or - most likely - dead.

So having Affinity on Linux would be fantastic for gfx professionals.
