The roles listed by NMR are a filterable multidimensional array, so you could try something like this in your theme’s functions.php:

/*
 * Sort the NMR roles
 * @param: $roles an array of all available roles with ID=>Name
 * @return: array
 */
function kia_sort_roles( $roles ){
	if( is_admin() ) {
		$array_lowercase = array_map( 'strtolower', $roles );
		array_multisort( $array_lowercase, SORT_ASC, SORT_STRING, $roles );
		return $roles;
	}
}
add_filter( 'nav_menu_roles', 'kia_sort_roles' );

Keep in mind that NMR displays the roles left to right before starting a new line.

So the roles will come out like:

A B C D
E F G H

and not

A D
B E
C F

I hope that helps!

You’re welcome! I’m glad it worked. I probably ought to display them that way by default.
