We have cargo holds for our airplanes and railcar bins for our trains. It would be useful to have shopping carts for our townspeople's orders. These carts would reserve and segregate goods for specific orders and prevent them from being used for other purposes. It would also remove them from the barn inventory as they wait - much like a plane or train - for delivery of the completed order. You would click on a townie, his/her shopping cart would come up and you would begin filling it. The way it works now, goods can be "stolen" from one order to fill another order or train bin or plane cargo hold...sometimes without the townie or mayor even realizing it.
