I just noticed a little bug with some skins when the Player Control Panel is located at the bottom and it plays a track with no stars.
With some skins (Iron Pyrite and Mellow Yellow II) the stars to rate the played track on the Control Panel have the same colour as the bottom Control Panel background, so one can't see it:
Could you also have a look at the bottom Control Panel in skins such as Beer Bee, Nacho Bee, Purple and Watermelon
When a track with no stars is played the rating stars could be hard to see (at least with some monitor settings).
Consider increasing contrast of the stars at the bottom Control Panel background.
Thanks for creating so many great skins
