This feature would allow the leaders and co leaders to lock someone in so they can't be kicked by anyone but them or a higher ranking person
to better explain here's a chart
Leader:can lock in elder or member and they can't be kicked no matter what but they can still leave if they want
Co-leader:can lock in elder or member but the people they lock can be unlocked/kicked by the leader and can still leve if they want
Elder:cant lock in but if looked in can leave
Member:can't lock in but if locked in can leave
When locked in a small green closed lock will appear next to their name saying that they are locked in
