1. Add an eject button next to the device name for the purpose of safely removing it (would function the same way as right-clicking and selecting "safely remove" but is takes one less click to do).
2. When deleting songs off of a device, the folders the songs were in don't delete. This is a pain for me because I like to sort by folder within my mp3 player, so I have a bunch of empty folders laying around that I have to delete manually.
