UI suggestion: Adding a friend doesn't give a confirmation

Hi,

Clicking the add friend button in the pop up doesn't confirm if the request was sent. Not sure if this is a bug or was just never implemented, so if something is wrong let me know. If it wasn't implemented, I think it should. Doesn't have to be something you have to click on, just a little notification like for when you get game invites would be good. Or simply put a notification in the same popup for sending the requests. Leads to a better UI experience for the average user.
