I need to have more control over the parallax feature. As I've seen suggested multiple times here, the ultimate solution would be something like Joysticks and Sliders- the script for AE from aescripts.com. If that's not possible, I'd at least like control over X and Y strength. I really just want X movement, but there doesn't seem to be a way to control this.
I'd also like the option of being able to drag the parallax around with the mouse rather than having to turn my head. In practice, physically turning your head to the side is pretty hard if you need the character to stay there while you do other actions. Then you can't see what you're doing until you look straight again!
