With the playlist node open in the left sidebar navigator, hovering over a playlist shows a popup with the total number of tracks, the total file size, and the total time of that playlist.
I feel it would be more convenient, and helpful, to have each playlist display the total number of tracks contained therein. One could then tell at a glance how many tracks there are in a given playlist. If the user wants more information, they could then hover and get the same information as shown currently.
This is the way playlists appear in Subsonic/Airsonic
Thanks for considering.
