Friends List Groupings

What I would like is some groupings for my Friends List that are customizable, as I have so many I sometimes dont remember who everyone is.

You would be able to customize their name and their placement.

Example of Current Friend List: (with random names)
My Eyes Burn
In Soviet America
Rise of Ghandi
ZOMG RAGE QUITTERRRR

Example of Modified Friend List:
PvE Allies:-In Soviet America
-Rise of Ghandi

Team Arena Group:-ZOMG RAGE QUITTERRRR
-My Eyes Burn

Basically making it easier and more organized.

I'd love the ability to split my friends list up into different contact groups, similar to Instant Messenger programs. I'd also really like to be able to add comments to all the people in my friends list, just a few words next to the name would be enough.
