I think it would be really handy to add a column to the "Allocated" pop out window in the Availability module, which shows the Required by/Ship by date of the order.
We often pre-sell products weeks or months before they arrive. Then once the stock arrives they are fulfilled in priority according to the Ship By/Required By date on the order.

Another improvement would be to have an "Only Active" checkbox (just like the Inventory > All Products page), so you can filter out any products which are marked as "Deprecated" or "Set up Required"
