The idea was to maybe have a dedicated “Metronome load library” app in the App menu. When you open it, it automatically shows the last setlist that was played via the app. The setlist would be saved on the Core, so could be accessed even without the phone. To switch it to something else, simply load another setlist with the app and it will be replaced on the storage of the Core.
But not 100% sure yet. Of course there are even better implementations than that - it’s just they also may require a special user interface on iOS or Android and more work (hence will take longer before we can release it)
