First up, excellent job. I love the software and the skin maker. Very well done.
I had an idea that someone might wanna consider for coding into a skin or maybe adding it to the actual next version of the software for volume control.
How about a vertical scroll bar that pops up when you press a single volume button so you can move directly to a volume rather than pressing up or down for a few moments. You could even drag the volume along the scroll bar.
I don't know how easy it would be to implement that but i just thought it would b useful.
