I would like to see the ability to add Group ID/s to worlds.
This would give world creators some moderation control on who can use their worlds. If no Group ID is provided anyone can use their world, if a Group ID is provided only that Group/s is allowed to use that world.
This comes from a problem my friends have been having, they run "Glass Office" a virtual office space for vr workers and lately a lot of erp groups have been hosting group public's out of their world. I know a lot of event/dj worlds could also benefit from a feature like this.
This Group ID system would give world creators the ability to control what groups could use their world.
