TAO, what do you mean by columnlist? Do you mean the Smartlist or Playlist column?
And were can I find "Last Played" in order to add it there?
He means the columns in the main view (Name, Rating, Album, Track#, etc.). If you right click the header a drop down list will appear. Scroll down this list and add the Last played column. (see attached screenshot)
Dear Brian
What do you mean by leave the playlist in Playing now? When I play the list favourites for example I do not see that in the Playing Now at all?
You can see the Playing Now in the navigation tree on the left, It contains couple of things. One is called zones. By default, MC comes with the Player zone (I think that's what it's called). When you press the Play button in a playlist, it sends the playlist to a zone (Player by default). You can see what's in the zone by clicking on it. I have several zones in my Playing Now (Music, Music (Rate), Player, Video, Workout). (see attached screenshot)
