Thanks for the nice responses everyone.
I tried a light gradient with an outline for the menu background initially, but changed it to something more Mac OSX style ... unfortunately, since I have to tile the background with the pattern, I can't have an outline (and no drop shadows like with the Mac). Unless knickelfarz has another trick up his sleeve, I'll probably deviate from the current background to a light gradient with a dark outline.
I tried to make the gridlines in the list blue tinted like iTunes (and to match the scrollbars), but the color MC9 uses is derived from the color of the separator bars. So, to get blue gridlines in the list, I had to have blue seperator bars, which looks awful
I may change the buttons to clear (to match the play/pause/ffw/back buttons) and rollover to blue ... then I could change the scrollbars to clear also. This will, of course, have to wait until tonight as I'm at work right now.
I may try a mini-me skin after the GUI changes settle down ... probably won't be for a while though. Much more involved, but if anyone has some interesting ideas, I would appreciate them. Insomniacs have to have something to kill the evenings
