Feature description:
Currently Symphonium let’s us create online only playlists. But there’s no option to add tracks (from the same server) from other offline playlists.
Ability to import tracks from other playlists from the same server/provider into online only playlists would be a great addition to playlists management.
Problem solved:
Ability to merge different playlists, convert offline playlists to online only and vice versa
Brought benefits:
Unique addition to the app which will help improve playlists management
Other application solutions:
I am not sure about other apps that have implemented this.
