Usernames on top, lifting username length restrictions

As for the Username + Full Name (+ Title) on the other hand, this still feels wrong.

I disagree, I think it works great.

I believe one workaround is to edit your full name to make it equal to your username. I think we suppress the full name in this case since it would be presenting duplicate information.
