I was messing around with my docks today, 2 zoomers, and was thinking it would be cool if you could have multiple layered zoomers, like, 2 rows, and they'd swap over when the mouse passed a certain point.

and the ability to make the background take up the entire edge would be nice, instead of it stretching every time.

And yea, edge detecting for zoomers, having two or three icons disappear of screen when you zoom on on any can get a bit annoying.
