When Editing Address in Orders add Profile Address Section
Customers make lots of mistakes in their addresses on their orders. I find this more true with mobile users because its more harder to type and sometimes auto correct screws up the address. When we notice a mistake in the address we try to fix it. Currently when editing addresses there is a bill to and ship to address and when a mistake happens it has to be fixed on both sections (assuming customer is shipping to billing address). However, it also needs to be fixed in the profile address, or the same mistake will re-occur on customer's next order. It would be more efficient if Bill To, Ship To, and Profile addresses can be edited on the same page.

Maybe have a checkbox on the Edit Address screen for the order, where if it is checked, when you click the save button it will update the profile address. This way if an order needs a one time change, it can happen without updating the profile.
