Advanced last played info and future play info
Now, when I click on a row, I can see when the song was last played. However, it would be good to also have information about when the only author played last. Also, if the song is already scheduled in the playlist, there should be a notification: It is already scheduled to play in:... This would be very useful in jukeboxes, when there is no time to look at what songs are already scheduled long in advance.
