Biggest thing making it “unstable” is the fact that it’s missing smart playlists. I have to say that quietly, as there are people ready to throw things at me. Once that’s there, a web-based playlist editor is the only other thing I want in the next stable.
I just finished moving. (well, finished moving OUT, not moving IN), so hopefully if my wife stops giving me HUGE lists of post-moving chores, I’ll have some time to finish all that up.
Anyway, give it a try!
