There are so much work and responsibility for UI module it’s really hard to take care of them. New features should get UI pass (or get icons) and there are also huge pile of backlog tasks. There are also new big ongoing features like asset browser and pose library that feels like more about UI than technical implementation in a sense that they really want to make it perfect from UI/UX standpoint.
From time to time I go to UI workboard and look at tasks, especially that listed todo tasks such as this. This one for example more or less up to date since Julian Eisel looked at it in late 2019.
There is also a lot of patches for UI which is good but those should be checked by people such as Julian. So while they are making it easier by doing most of work there are still bottleneck in review process.
So in current state of things it’s perfectly normal to feel like many things aren’t addressed but it’s definitely better with additions such as this one.
