Create separate circles of people for one Lifecake stream.
I would love to share the Lifecake imagery and video with a variety of different friend/family groups in my life, but it would be more appropriate for their communication streams to be separate.
I saw another person on the forum ask if you could hide comments so that one one person didn't have to see the comments of another family member/friend. Having seperate circles could be another way to meet that need. The two people that don't get along would never be in the same circle.
