Is there a reason why there are two different sized .jpgs for many items.
It appears the buttons are actually identical other than a larger (5 pixel) black border. Seems we could eliminate alot of these buttons if we just stick we a standard.
I'm thinking we could eliminate the duplicates of: Search, Playlist, Queue, History, Decades, Top 10 and maybe a couple others. Since I don't see "Filter by Genre, Artist, Year" in the 90 size - I'm going to assume 85 is now the standard and the overall button size has just been cut down by deleting some black pixels on the outside of the buttons.?.
I just started working with the skins so I maybe missing something, let me know if I am.
Might save a fair bit of space by getting rid of the images that are not used.
