Plugin Improvment

Hello! Can you improve your plugin for hiding category in WordPress Category Widget?
Example code:

function exclude_widget_categories($args) {
	$options = ksuce_get_options();
	$exclude = array();
		foreach ( $options[ 'exclude_main' ] as $value ) {
			$exclude[] = $value; 
		}
    $args["exclude"] = implode(',', $exclude);
    return $args;
}
add_filter("widget_categories_args","exclude_widget_categories");
