That's exactly what made Krita so good. Every once in a while they'd shut a bunch of the developers in a room with a bunch of artists/users, have the users complain about everything that pisses them off, and get all those things fixed. The resulting application is obviously driven by what artists enjoy, and it feels that way. Strongly recommended.
The stupid pandemic has made that impossible for us for quite some time, but our current workflow of having artists discuss stuff on krita-artists.org with developers listening, then making a plan and then working on works quite well for us.
But I miss the sessions where each artist present would have two hours to demo making something with the express message: tell us what you hate, and we're not allowed to tell you "oh, but you could do this using that."
