New 9.7 Undocumented Feature: Player Notes

Good morning everyone!  I just found some screenshots made by Alexjamesrook (reddit), of a new feature: Player notes. They work like small descriptions/a kind of WoT post-it (for remembering stuff later) to me.

You can only do this from the contact list so they have to be a friend, clan member, or black listed (or recruit but those should be on your friends list):

As far as I can tell, you’re the only person who can see the note.  Just hover over their name in the contacts list and the note appears at the bottom.  There’s also a small icon for people you’ve made notes for.
