Unable to enable/disable Friends and Requirements Links once session has started, and control their behaviours.
Once you start a session, having friends or requirements links are somewhat set in stone.
I'm aware you can add requirements links via the API and that works with a user who never had it enabled originally, but you can't enable friends. You also can't change their behaviour (add/sub/random option) on the fly. I think the holder should have access to this, and they should also be able to control how many links the wearer needs to have directly - presently the wearer has to add them, or give their API details over and must give their API details over to the holder to have them removed.
