If you ever worked professionally with PS, you are getting tired of recommendations of tool that is capable like 20% of PS.
Creating a specification for minimum viable features of a raster editor able to replace Photoshop would be fantastic.
Could serve as a roadmap for alternatives and for bragging rights: "Painter2900: implements 99% of the Rasterflames Liberation Standard, and more!".
Beside functions, Gimp's UI looks outdated.
Krita on the other hand is basically everything I remember about old Photoshop. Even the keyboard shortcuts are pretty much the same. The price is quite right too.
What Adobe has done with generative AI has been really impressive though. I am going to probably have to give PS a try just to see what I am missing.
