I would like the ability to edit shipping labels. I have had customers place more than one order from me back to back, and there was no way for me to combine shipping after they had already purchased both items. This was frustrating because they had to pay for shipping on both items, and I was not able to combine the orders into one. It seemed really stupid and wasteful for me to have to send two separate packages to the same address. Also, I would like to be able to see what the weight of an order is when someone purchases more than one item from me. This would be helpful because then I could see if the new weight was accurate. If it wasn't, then I could reimburse any shipping overages.
