Character List with alts

[Matoskah]

Since our friends list is never long enough could someone create an addon which you could list character names and list or associate all their alts with that main character name. The add on "Bad Player" caught my attention for this but that one shares information with guild which i wouldnt want to do. It would be nice if this add on shared that names list with all your own characters on your account.
NotesUneed is also functional but way too elaborate and it works off your ingame friends list also therefore running out of slots for names.
Thanks

Prat has this functionality in it's AltNames module (IIRC it's off by default).

I think that is too in Chatter, never used that options called "Nom Secondaires" in french , Alt Names i guess for english, but I think its used for what do you need
