My Foobar Config:
Tried to go for a nice simple config. Uses default UI.
If you're having issues with the playback controls crashing making sure that WSH Panel Mod is not in safe mode (check under preferences).
Update 1 (11/2/13) - Added foo_wave_seekbar. It appears that when foobar installs it with the component package, it doesn't go in the components folder so it wasn't included with my install. Just double click the file in the main folder and it should install in foobar for you.
