I've owned a copy of AS 2 (And recently, 3) for a couple of years now. It really hasn't been an issue until I just started using it (in earnest) to create a game world (galaxy?) for a d20 Modern/Future campaign.
I find that navigating around my galaxy is really, for lack of a better term, tedious. So my request is perhaps some sort of arbitrary movement such as a "WASD"/mouse look way of moving the viewer around. Otherwise AS is a fantastic tool, I'd be lost right now without it
