How do I turn off the next/previous buttons which appear on each of my products. I have several products with lots of options and my customers think that the next previous buttons take them to the next step in configuration of the product and many times give up after spending all that time to get the product configured just how they like it only to navigate away to a different page. I see in admin where you can set them to top, bottom or both but I would like to remove them all together. What would be the easiest way to get that done?
