mailusers_get_roles() function to use the core get_editable_roles( )

Is there a chance that you can change the mailusers_get_roles() function to use the core get_editable_roles( ) function?

I’d like to use email-users but I don’t want to open up all the site roles/groups to users who just have the email_user_groups capability if they shouldn’t be able to see a particular role. The standard WordPress get_editable_roles( ) function allows for roles to be excluded from users and it would be great if email-users could take advantage of this flexibility.

The current function mailusers_get_roles looks like this ..

function mailusers_get_roles( $exclude_id='', $meta_filter = '') {
	$roles = array();

	$wp_roles = new WP_Roles();
	foreach ($wp_roles->get_names() as $key => $value) {
		$users_in_role = mailusers_get_recipients_from_roles(array($key), $exclude_id, $meta_filter);
		if (!empty($users_in_role)) {
			$roles[$key] = $value;
        }
	}

	return $roles;
}

I suggest this..

function mailusers_get_roles( $exclude_id='', $meta_filter = '') {
	$roles = array();

	$wp_roles = get_editable_roles( );
	$wp_roles['roles'] = $wp_roles;

	foreach ($wp_roles as $key => $values) {
		$users_in_role = mailusers_get_recipients_from_roles(array($key), $exclude_id, $meta_filter);
		if (!empty($users_in_role)) {
			$roles[$key] = $values['name'];
        }
	}

	return $roles;
}
