Hi, there is a contrib to add an all_products.php which lists all the products under their categories, but no images and they can click on any of them as a link. I have also installed a contrib, I forget what it is called now and I have to go out for a little while, but it puts all your categories with subcategories on the front page with links to all. I can get that info later if you want. I am not sure what you are looking for, so I don't know where to direct you. Also, I have found that the "New Products" link actually shows all my products! so on my husband's site I just changed the wording a bit to say "All Products" instead of "New Products" and I believe that I took it of of mine as it is not necessary for it. You may gladly check out my site allaboutwicker.com or my husband's new smaller site floridaautooutlet.com and see if any of my changes are what you are looking for. I have to go for now, but will check in later to see if you responded and would like more info.
Hope this helped,
Leslie
