    Great plugin thanks. I use private pages to control access to documentation and by default this plugin won’t show private pages. I have added this capability as a short-code attribute, pasted the code below (file ccchildpages.php), all altered lines contain “post_status”.

    
    <?php
    /**

    	public static function init($value=0) { self::$cc_id_counter = $value; }
    	
    	// Get unique ID
    	public static function get_unique_id() {
    		self::$cc_id_counter++;
    		return self::$cc_id_counter;
    	}
    	
    	public static function load_plugin_textdomain( ) {
    		load_plugin_textdomain( 'cc-child-pages', FALSE, dirname( dirname( plugin_basename( __FILE__ ) ) ) . '/languages/' );
    	}
    
    	public static function show_child_pages( $atts ) {
    		// Get unique id for this instance of CC Child Pages
