I would love to have an option to create groups or “pools” with friends - so when one friend sets up a new PMS, they don’t have to go and share their library/libraries with everyone else individually and the rest of the group doesn’t have to go in and share individually with them. This happens a lot with my work friends - 5 of us have to add the new guy and the new guy has to add all 5 of us. It would be much easier if we could just invite them to join our group. Or when one mutual friend finds out another has a Plex server up - they can share with the entire group of friends rather than needing to go find everyone individually. Permissions/roles could be assigned by a group admin (“can invite new users”, “can add new users”, “can remove users”, “group admin”, etc.).
If someone had a particular library that they wanted to share with individuals but not the whole group, they could still do that with the existing system. A feature could be included to allow users to block specific content/libraries from members of the group if they chose to.
