Product Navigation allows you to show all your products in the navigation instead of just categories or manufacturers. This is especially useful for sites with a small number of products.
It can be configured to target any widget zone (default is left_side_column_before).
Can also be configured to either show products only, or group products by category or manufacturer.
Plugin can be seen on our demo page at http://demo42.karovastage.com/ on the navigation menu on any of the category pages
