I cannot agree with you. Not until most of my UI improvement requests over the years get done. Like adding folder to draw order list and don't put everything (events, hierarchy, draw order, constraints) in the same panel to avoid sharing selection, dedicated selection group UI, shared color picker for bone, slot and attachment, make it possible to control the color of a sub-tree instead of having to adjust each slots in the sub-tree, and many more I don't even remember.
I have not been doing spine for many months as I am focusing on other kinds of works like coding. I really hope they can put more focus on the UI so that when I return to do character work, it could be more enjoyable... Nah, just joking, I don't have hope on those requests anymore. I just hope that when I upgrade my runtime to a new version in the future, things won't break.
