Chest Permissions - Set to Owner Player only or Share

Please can we be able to set permissions on our chests so that only the chest creator can open it, or have it set to share. So the chests can't be raided by others who may visit your realm.

Alternatively/Additionally, allow players to close their Abeyance realms from visitors, even if the visitor has an address card. So visitors can not come to your realm when you are not online.
