Share 'No way to edit friend's names anymore?'

I've been a member since 2004, and I remember being able to edit the names of how my friends on the friends list appeared to me. I did this so I'd remember where I befriended them from (which message forum, group, etc.) Now I can't figure out how to do that. Did they remove this friend feature too? The names I edited previously are still showing up as edited.
