Twitter-like Ajax Instant Pager for Magento
Show More Products Ajax Pager extension implements contemporary and exceptionally handy way to show products in catalog product list page. Old-fashioned pagination is removed with one Twitter-like button saying "Show More Products" (or any other text of your choice). When user clicks on this button a new portion of products is loaded simultaneously on Ajax, without page reload. Moreover, products that have already been loaded previously - remain on the page. So the user will see all the products in one place, on one page, without a need to look though dozens of pages again and again in order to find a product he liked.
