I've been battling all sort of glitches for the past week since I've switched to 2.70 and now it's too late to go back so let's try to fix this stuff - depth at least.

https://www.youtube.com/watch?v=qychF11jFTw-what is depth sort - in comparison with the old behavior - I noticed in the past that sometimes moving in z a widget would make it overlap, other times, not, now it's consistent but still doesn't work all the time: play and edit mode are different.
-with depth sort on, can there be a panel inside a panel? if so how does panel sorting work since panels don't have a depth?
- why is the green square representing the panel displaying far behind the root of the panel?
- when a panel is in the pre 2.70 mode (I defaulted back to it) when you move a widget in z, suddenly a group of widget will snap in front/back of another group... what is the logic of it?
Oh and it would be nice to have custom inspectors work with multi selection (and I'm glad you're not allowed to make fancy inspectors in the Unity UI ;-)
