friend list subdivisions

[Majidah]

Request for 2.0

I'd like to subdivide my friend list.

Sometimes I befriend people who are good at certain event and know they are interested in doing it some other time, but I have to keep track of who is who manually.
I'd love to be able to divide my friend list in categories like

• "People who do garuda"

> name
> name
> name

• "Friends"

> name
> name
> name

• "tanks"

> name
> name
> name

Maybe even put annotations or labels. Like (DRAGOON) by a player's name, to remind yourself he has a geared DRG
