I would like for the ability to edit or remove an Item from a Store Order. This is useful in case we are actually out of stock of the physical Item and would like to reflect this on the invoice. Also, this would make the Invoice Total different than what they paid, the ability to issue a refund would also pose useful.
We need to be able to edit item size etc. or delete items due to user error. We now have to keep track of these separately and this leads to errors in ordering.
