I love this new feature but the other day I was following the motion path of a later I had sent waaaaaaay out beyond the comp into the pasteboard and eventually I couldn;t see the dots anymore and got lost. I tried desperately to find my way back to the comp screen but was basically just grasping at thin air since I had no way of knowing what direction I was traveling in or where the comp screen was with respect to my location in the pasteboard.
Luckily all it took was a magnification change to pop the comp window back to the comp screen.
Cool feature, but it does make it possible to get totally lost in the grey abyss of the pasteboard...
