Was thinking about this today, as i love doing family history research.
I wonder if a better way is have a relationship tab on the top.
Say if i chose my wife’s mother, i can add in her parents and siblings and children.
Then when i choose my wife i can add her husband and child into her profile.
That way each person will have their own unique list of photo in the relationship manager.
As at the moment its all set for one level if you know what i mean.
