Multisite setup to apply across network?

A possible workaround I wrote up with that I might try (without modifying the plugin code) that can be put in functions.php or another functions library of sort.

This would force the settings page to use data from the root blog (blog id 1) in a multisite setup. It would also redirect the settings page to the root blog settings page.

/*
 * Override for WPFront notification bar plugin for sharingdata from wp_1_options for site wide settings
*/
add_filter('option_wpfront-notification-bar-options', 'override_notification_bar_blog_options');
function override_notification_bar_blog_options() {
	remove_filter('option_wpfront-notification-bar-options', 'override_notification_bar_blog_options');
	$new_value = get_blog_option(1, 'wpfront-notification-bar-options');
	return maybe_unserialize($new_value);
}
/*
 * Redirect for WPFront notification bar plugin to root blog settings page for site wide settings
*/
global $blog_id, $pagenow;
if( is_admin() && $blog_id != 1 ) {
	/* Check current admin page. */
	if($pagenow == 'admin.php' && $_GET['page'] == 'wpfront-notification-bar') {
		wp_redirect(get_admin_url( 1, '/admin.php?page=wpfront-notification-bar', 'http'), 301);
		exit;
	}
}
