Choosing to use either categories or attributes

Is there a way to set up LiteCart to use either categories or attributes, depending on an end user's choice?  I think it would be good to give the customer a choice of using categories or attributes - whichever one they feel more comfortable using - via a menu or button on the main page.

Instead of using pages/category.inc.php you can create your own file that generates a listing the way you want. Loading a category will load the category's contents. Loading a manufacturer page will load the manufacturer's products.
