siliconsys.com is preparing to release two new modules Product Browser and All Products. They are currently in Beta release. If you would like to be a beta tester of either of these modules and have some input into the final versions please contact us for further details.
Product Browser
The Product Browser module adds previous and next product links to the product detail templates. This allows your categories to easily be browsed at the detail view level.
Estimated module cost: $20
All Products
The All Products module provides a list of all products in your catalog. The list can also be broken down by category by passing the category ID in the URL. This module is great for giving search engines a list of all of your products in one place. This can shorten the amount of time required to get all catalog products indexed.
Estimated module cost: $25
