Favorite friends.

I like checking my friends streams and stuff a lot but sometimes I have trouble finding them in my friends list or leaderboards because I have so many people added due to wanting to expand my music taste and that helps a lot. Basically what I'm asking for is a option to favorite friends so they're like at the top of my friends list and also have their own section in the leaderboards. I think that'll be a very cool feature to have for my friends.
