Suggestion: Display public name, use display_name instead of user_login
The title of author page display the login name which is not user friendly, display low case text and not pleasing to readers. Exposing login username to public opens security vulnerability to hackers.
I suggest, we use display_name instead of user_login
file: include/theme-functions.php (line 106) : $current_user->user_login
