AbleCommerce Shopping Cart Software

This is something we had on another software -

I'd like the option to remove the item from customers view when out of stock. This would be very helpful on clearance items we never plan to carry anymore.

So when the inventory hits 0 the item just goes to hidden.

If you could have this as an option, so you could select if the product would not be displayed when it hits 0 stock level or displayed and the customer offered the chance to backorder the product, that would be great as this flexibility would meet our needs.
