Another suggestion related to stock that is controlled by options...

It would be nice if there was some simply javascript where it would change the Add to Cart button to the Out of Stock button based upon the option that is selected. I think it would make it a little more intuitive for the customer to sign up for stock notifications. Currently, if the stock is controlled by options, the OOS button style and text does not show up when the option is selected. They can sign up if they know to attempt to add it to the cart, but it would be a little better I think to have the button dynamically change, or some other mechanism that signaled to the customer how to get notified, depending on if the selected option has stock. Thanks!
