I have searched the existing feature requests to make sure this is not a duplicate request.

The feature

While I can favorite photos in albums shared with me, it is difficult to browse them.

One part would be in the shared album view:

• display the favorite icon on photos on the album overview
• filter by favorites List of all favorites from shared album (query the database?) #11290

The other half is to allow inclusion & filtering of the favorites tab to also include shared albums etc.
