I've added a request here that includes the addition of Send To which would allow you to send a track to a Playlist from the Player: http://www.ventismedia.com/mantis/view.php?id=8391

I would like a quick option of adding the current song that is playing in the player to a playlist. I often edit my other tracks so it ends up adding that selection to the playlist and i just want to either be able to jump to the current song that is playing or have a pop-down playlist menu in the player that I can use
