Description

It's a bit annoying that the current line item keeps jumping around the invoice window. It's not too bad for a couple of items, but if it's a large ourchase you are never quite sure where/if the new item has appeared on the list.

By default each item should appear at the top so you can keep an eye on it and make sure the correct item has scanned.

At the moment the new item apeears almost anywhere depending on the name/product id etc and what ordering has been left behind at some point.
