I think one feature that would be extremely handy would be to be able to switch between vertical and horizontal menus. I currently have around 38 main playlist entries, which are the artist names. If you want to scroll through, it takes forever. (Yes I know about the number key shorcuts, but that doesn't help if you just want to browse quickly through the list.) If the user were given the ability to switch to a vertical menuing sytem, then you could easily show 4 artists at a time, instead of really just one. I can't imagine this would be a difficult change to implement.
