How do I have a Winamp / MediaMonkey style “now playing” playlist?
Unlike winamp (and mediamonkey), there is no special “now playing” playlist in foobar; the foobar way of doing things is to play playlists. That said, you can use the playback queue to get a similar functionality. Instead of clicking “play”, use the “add to playback queue” command. You can use foo_uie_queuemanager component to display a panel that displays queued songs.
