Make sure we tests the look of the selection panels for our different view classes.

Looking at the screenshots we can see a lot of room for improvement.

nice! This should give the next person changing anything related to view properties a good idea of the consequences!

A bit unfortunate how much a lot of these uis relies on having a frame run to show something.
Would also be interesting to expand all of those 🤔
