May I ask why you switched to ELPlaylist (as opposed to ESPlaylist in FooAero)? I don't understand how to update my playlist with newly added items. In FooAero I would right click on ESPlaylist, select Playlist -> Follow Library, use ctrl+A to select everything, and switch back to Active Playlist, which now included any new items added to my library. Follow Library is no longer an option so how do I update my playlist.
ESPlaylist also had an Operations entry in it's right click menu which allowed filtering of the list with modifiers such as bit rate and date modified which I found very useful. I guess these are no longer present in ELPlaylist?
