@jancborchardt @marcoambrosini @nimishavijay do we wan this?

I would say yes. I guess that on Nextcloud itself it wouldn't be frequently used, but we know that many users use NC to sync contacts on their phone, where favoriting is a much more commonly used action, so I see a strong use case for point 3.

In the UI it could be fairly straightforward since we have a common pattern for adding favorites.

• The action could be accessed from the 3dot menu of each contact
• there could be a navigation item "Favorites" between "All contacts" and "Not grouped"
• If a contact is marked as favorite it would have the star in the top right corner

How do we handle localization? I'm assuming it shouldn't always be starred but use the user's language. Yet that might be problematic when someone shares an address book, then a common name would make it language independent.

@avinash-0007 could it be possible to localize the group display name but have a consistent identifier?

Wouldn't a better solution be to allow a user to prioritize groups; to add a manual sorting method to groups, and then add a button to add a user to a group on each contact entry? It'd certainly be more versatile. I think it'd be the better option, because other contacts apps might not call their starred contacts starred, so it'd mitigate certain sync disparities.

I would not localize it i would let the user decide how he wants to call his "starred" category
