Name Changes

Hello! I've got a small idea for Discord. I was thinking, that maybe when a discord friend changes their username, their friends should get a notification stating that? I've been confused when I log into my account and see that an unfamiliar username is in my friends list. It could help prevent confusion, which is something I definitely can relate to! Also maybe underneath the users name for a day or two, it could state that their name has been changed? Sorry if this is super confusing.
