It would be nice to access and share Roon playlists with other Roon users when outside of the wifi network. (E.g. at a friends house)
Often times would like to recommend or share tracks from playlists but they are not accessible when roaming and as Roon does not save to Tidal playlists, this would be nice.
Simple suggested solution would be to make Roon server backup playlists to a cloud drive and then enable Roon mobile app to access them on the cloud drive via internet. (No access to roon server would be required which would demand more complex implementation)
