Setting to remove button_add_small (Quick Add to Cart)

How can the quick add to cart feature be removed via setting or even template edit? I'm talking about the little + button that quickly adds products to the cart.

At this time it must be removed from the tpl file. In 1.4.9 I will add the option to remove it from the admin area

Which tpl files please?

catalog/view/theme/default/template/product/category.tpl

Find and delete this code:
If you don't want to modify the template, a quick and dirty way to accomplish this is to rename the image button_add_small.png (in catalog/view/theme/default/image) to button_add_small_old.png (in case you ever decide you want to use it again), and then upload a new button_add_small.png that is a 1 pixel image.
