UPDATED: Playlist Manager v4.3
The Music app only allows one playlist to be selected at a time. This applet can perform common useful tasks on a multiple selection of playlists: playlist title renaming (add text, remove text, search and replace text) and duplicate, delete, export, move to Playlist Folder and merge playlists.
- Officially compiled as Universal
- Commensurate improvements for M1 Macs
- Fixes issue with "Duplicate" tool
- Minor performance and UI enhancements
