Multi-iCloud-user (family) library support

Currently Infuse very cleverly syncs manual library modifications across devices via iCloud. It’s not uncommon to have to fix matches because of poorly named files, so this is a huge boon. Unfortunately this benefit/time-saving only applies to devices logged in with the same iCloud account. e.g. my iPad and an Apple TV share changes, but my mother’s iPad does not.

I would propose that for whatever iCloud record is being used to sync these changes, Infuse use the native CK/Add-People functionality to allow other iCloud user’s to be added to it. Then a setting somewhere in the app for the current user to select which library they would like to use, their own, or a shared one they have access to.

P.S. Please add fully library metadata syncing across iCloud too ?
