I'd like if iTunes would keep playing the album I told it to play, even if I'm browsing around the rest of the library. Right now, it will just stop after the current song finishes, if you've selected (not double-clicked, just selected) another album. It doesn't start playing the newly-selected record, which would make a sense, it just stops playing the current album.
What's the point of that ?
Used to be my biggest complaint (of course, after “you can’t have more than one Library”). The most recent version of iTunes has solved this problem. It could just be fixed for macs though.
