[REQ] Fill cart with customer previous order with one click

I read somewhere that previous order info was stored in a cookie.

It would be great to have a one-click fill-cart-with-previous-orders-products button. With the store I'm currently working on, the customers often order the same (or similar) stuff.

Of course, it would have to check inventory and if the product exists on the fly, but still seems like a good idea.

Anyone with me or am I alone on this one?
