Show user login name in posts/pages list to avoid confusion if identical names exist

[Presskopp]

Assume there are multiple users with different username, but both the same public name.

The posts/pages list (which is controlled by class-wp-posts-list-table.php) will show the Author twice (or more) under the identical name. I wonder if it would be helpful to (also) show the real username (in brackets) so this can be avoided.

Compare to when setting an author of a post - it will be there already.

This ticket is to open discussion if this is useful or not, and how it would be implemented in a manner so it's helping information and not overload. Thank you.

My initial reaction is that this feels like plugin territory and we might be better off with a filter in get_edit_link. It seems like it would be an edge case.

I agree with @jorbin, it does seem a bit like an edge case.

We could add a filter to WP_Posts_List_Table::get_edit_link(), but that would be inconsistent with WP_Media_List_Table, which doesn't have a corresponding method.

That said, both WP_Posts_List_Table and WP_Media_List_Table use get_the_author() to display the author name, so adding a user login there is already doable via the_author filter:

function wp40564_add_user_login_to_author_name_in_admin( $display_name ) {
	global $authordata;

	if ( is_admin() && is_object( $authordata ) ) {
		$display_name = sprintf( '%s (%s)', $display_name, $authordata->user_login );
	}

	return $display_name;
}
add_filter( 'the_author', 'wp40564_add_user_login_to_author_name_in_admin' );

Given that there's not additional requests for this or a single plugin dev commenting here looking for a filter to do this, I'm going to close this as wontfix.
