Works great on my MacBook running 10.4.7. At first I thought there was something wonky with its handling of the Apple Remote's menu button because it seemed to cause a random jump to a different letter, and only for the albums in the background, then I realized what it was doing was toggling the sorting between album name and artist name. Cool. On the other hand, using the volume up and down to change tracks instead of volume is weird. I'd rather it worked as follows: The menu button would toggle between controlling iTunes and controlling CoverFlow, preferably with some visual indication of which is in effect (and easily seen from a distance.) A good way to do this would be to have coverflow switch to a different view when you start playback (or pressed menu), one that showed the album art, track info, play time, etc, of the current track, and the remote would control iTunes playback. When the user pressed the menu button it would go back to the library view, and the controls would then control browsing of the library. Pressing menu again would bring up the playback info again. Etc. It would be intuitive and more obvious. It would still be nice to have the ability to control the sorting via the remote, though - is there a way to handle press-and-hold on a remote button? Perhaps then a press-and-hold of the menu button would either change the sorting, or perhaps better, bring up a menu of options, including the sorting options. I realize this is all a rather tall order, though. :)
