UPDATED: Playlist Manager v5.1
The Music app only allows one playlist to be selected at a time. I mean, it makes sense. Select two arbitrary playlists and what would be displayed in the browser window? I’ll bet no one knows. I think it would be Messy. That’s my guess.
Playlist Manager v5.1 can perform common useful tasks on a multiple selection of playlists: playlist title renaming (add text, remove text, search and replace text, text transforms), change View, duplicate, delete, export, move to Playlist Folder, merge playlists and remove track copies.

Latest version:
- Minor UI update
- Maintenance
- Icon and docs update
