Yep, sidebar player is fixed!
I've had a recurring problem that well precedes 3.0, but I've never been able to pin it down. Sometimes, after I've been doing *something* with playlists or filters that use custom views, the "no filter" filter will mysteriously switch to the view I've been using in another node. I've seen it happen a few times in 3.0, too. Can you suggest anything that I might be able to test specifically as the cause?
