Feature request: First-name-only mentions

We have a relatively small team with minimal first name overlap. Mentioning @collaborators in a task comment using their full name doesn’t read very naturally. It sounds far less conversational.

It would be nice if there was some way of removing the surname. Facebook does this quite well with it’s mentions where it allows you to back space the surname, but preserve the first name (and obviously the intended recipient).

@Ben_Crowl I am fairly sure that if you get everyone to change their profile settings to just their first name that will do it.
