Pre-Order features

i am selling video games. so I would like to ask you to include these new features if it is possible:
• if you have items for pre-order and that item is available for pre-order, few weeks or months before the release date, it is really hard to find them between the orders. it would be really useful to sort the orders by items. so it will show me only the orders, which has the requested item in them
• it would be great to have temporarily disabled the BUY button. I believe it is still good to have the item liste, even if you know, that you can not get it anymore, but google will still index them
• if you cancel an order, it would be great to put that canceled item back to stock, now it only changes the order status.

i had some more ideas, but this is it so fat for the moment. hopefully you will consider to include them in the next versions of this great open source e-shop. thanks.

1.) might be in 1.5.0 (I think I saw something like that posted somewhere)

2.) you can edit your product.tpl to check on product_status and have the buy button show or not show. I did something different but based on time.

3.) good idea ... (hmmm, the cart doesn't do that ?)
