Spectating notification

So I just got into hearthstone, and they have a spectate feature just like league, where you can spectate your friends. Only in Hearthstone, it gives the player a notification that someone is spectating them. I thought that was really cool and I think that this could be implemented in league. It wouldn't really change much and is kind of unnecessary, but it's just an idea, and thats what the boards are for :D
