LF add-on: Friend login filter: Acquaintances

willandbeyond

I would like an add-on that filters friend logins. I'd like to be able to right click on someone in friends list and mark them as an acquaintance, which would then stop notifying me in chat of login/logout. This way I can still keep people in my friends list, and still see some people login/logout, but not everyone.

Does something along these lines exist?

If not, anyone willing to create it for for some gold (PC-NA)?
