Please consider adding a feature about a shipment not moving to the next stage in 'x' days. This is very important for us (merchants). Its quite trivial to find out if a package did not move from one stage to another for 'x' days. And if that happens, it will be beneficial to notify the merchant. We have been having this problem with Fedex and we ship out another box when we sense that some package is delayed beyond 10 days.
