Similar to the use (within Adalo) of external relationships (eg, importing those in Airtable - https://ideas.adalo.com/feature-requests/p/external-collections-support-airtable-relationships-and-attachments-properties).
This would give the ability to have relationships within Adalo between Adalo items and external collection items.
Use case - bringing in data (say, content) from Airtable or elsewhere and allowing a user to add it to their favourites:
  • new relationship in users 'external collection item' (one to many)
  • toggle to add/remove external item from favourites
