Moving tracks from playlist to playlist

I would like to have the ability to move a track from one playlist to another (adding to the new playlist, then deleting it from the original playlist) in one operation, rather than adding in operation 1 then removing in operation 2. Also, I would like to see a symbol added to albums, or tracks that show that they are already added to a playlist, maybe a “PL” in a circle in a corner of the thumbnail. And maybe a “L” in a circle if it’s in your library. I’m getting too old to remember what I have added, and where.
