Ability to change username in Dashboard/UI

[skorasaurus]

Hi,

I'm writing to politely request the ability to change usernames (adding user names so it shows up in search terms for others looking for user) in the UI/dashboard.
One common use case that I've experienced is that we assign our user names tas the person's first and last name (and middle initial if a duplicate) and the person's name has changed, needing to change the user name in wordpress as well.

I did a brief search of this in the trac with the summary of "username" and couldn't find a relevant ticket.

Hey there,

Welcome to Trac! Unfortunately search here isn't that great.

I'm closing this as a duplicate of the first one to keep discussions at one place.
