I really do love this app, but it is starting to suffer feature bloat at the same time that older, important features are breaking. I for one, can no longer get iTunes to respond in any meaningful way to what I do in coverflow:

double clicking an album starts a nice zoom effect, but nothing happens in iTunes.

while listening to a track in iTunes, and flipping through the album covers and double clicking one in coverflow starts a nice zoom, and the coverflow quickly flips back to the already playing track.

The stop, forward and back buttons do nothing for me.

Who knows, maybe its my rig, but all apps and OS are current...

It's still pretty, but I can't show off to Winblows people any more - once again my mac looks like tempermental, barely functional eye candy :-(
