Icons are not hard to read by itshelf. If they have a good layout that allow user to learn a shape is a better way to work. In the proposal the only that have a bad shape is the mesh edit subpanel.
But if we compare the base popup with the proposal is more easy to read and learn.
It’s true that the worst problem is the blue accent. that make hard to put near a lot of buttons. But I don’t think that devs will go to change this now when they have picked a mobile style. Anyway with a more smooth white the panel is better
