About iTunes Doodad
It installs itself as a tiny icon in the System Bar (up there next to your clock) and acts as a remote control for iTunes.
There are several preferences: choose which playlist types to display (Library, Smart Playlists, User Playlists, Podcasts, Purchased, Videos), and sort all of your playlists alphabetically (you’d think iTunes would let you do this, but it won’t…), some other stuff, too.
