Make Ae Comp Size change more flexible, by setting the anchor (like Ps Canvas Size).
Ae assumes that when changing the Comp size, the center should stay in the middle. But there are situations where whe want to extend the comp in one direction. In those cases, selecting an Anchor would be great. Just like in Ps Canvas Size.

You can do this already.
From the Comp Settings screen, go to the 'advanced' tab, and change the anchor point.
Then, when you change the comp dimensions, it'll change from the point you set.
