I wish people would refrain from posting reviews until they understood the nuances of an add-on. This module makes up for the fact that Joomla decided to stop plugins running on modules. It also allows you to centralise custom HTML which makes it easier for users (esp non-tech ones) to manage their sites. Well done and bravo...
One nuance:
helper.php Line 36
$results = $dispatcher->trigger('onPrepareContent', array (& $item, & $params, NULL ));
Added the NULL to prevent warnings about missing 3rd parameter...
