Snap to comp edges/corners/center
Allow snapping to the comp in the same way that's already possible with other layers. I thought this was already possible but it doesn't seem to be.
As in I move a layer, hold cmd/control and when it gets close to the upper corner of the comp, it snaps to it.
I can sort of do this with the align tools, but that doesn't work on 3D layers, and it doesn't work with groups of objects unless I first parent everything to the object I want to use.
