In the list of items in the receive screen it looks as though barcodes are editable directly from the list, this is not the case, as you manually must edit each item to change the barcode. It would mean less clicks if you could edit the barcode directly from the list, it would also be less confusing since it in the current design looks as if you should be able to do this. In the current design you can edit the text in the barcode field in the list, but any changes are not saved.

If the ability to change barcodes directly from the list were to be implemented it would have to also include a check for duplicate barcodes, like it does in the item editor.
