Group Chat needs to be fixed

Great app overall but the group chats need a huge overhaul hence my terrible rating. Simply because currently it allows trolls and other information seekers too much access to private information.

Needs the following:
- protection against photo grabbing.
- admin level members with control over notes section and chat timeline.
- admins need to be able to ban individuals from chat
- need to control who can invite to a chat.
