Are there any (non-default) skins available to "supporters" there are not lifetime members? I could never get the slider to work (without a significant delay) and I saw some of the premium skins have jump to letter buttons. There are also some cool features like showing the queue on the main screen and others, but basically the jump to is what I'm looking for.
Look in the V7 skin releases part of the forum, I have released free skins in there
