I know WC probably is too close to Final release to make any changes, but I thought of some things that would be nice for the future:
A toolbar, like G-Force has, to select configs on the fly.
More backgrounds and foregrounds (but maybe script writers can make those)
And a lot more preset buttons!! It's hard to only choose 5, because if another comes up I like, I have to erase a config I saved.
All in all, Whitecap has REALLY improved!!!
I like the rotating cubes and the "VU meter" bars!!!!!! Nice additions!!
