Yes like a nickname, except that it should be the primary name displayed to me for each contact in my contact list. Initially it would be set to their actual username, unless I customize it. Once’s it’s saved in my contacts, then it should only change in my contact list if I authorize it to be updated when you broadcast a new name to the network. If I don’t authorize it to change in my list, then I just keep seeing whatever nickname I have set for you.
