Friend list notes

Hi all,
I've taken a look to previous hints, and hadnt no found it, so i put here a little suggestion:
When addin a new friend in friend lists, and for existing friends, will be nice to have a little text note near him that i can edit, for example notes like 'xyz guild leader', or 'he borrowed my sword' and so on can be very helpful to just remember why the guy is there.
