I would like to suggest again the creation of a product display page which would show item name and counts to quickly see our stock levels.
Having to flip through each product takes too much time and difficult to get a quick overview of product levels.
If a larger product entry screen were created, most all boxes are too small, and a way to flip through each product quickly with an up/down button - and a counter showing how many codes or stock remaining then that would be even better.
The item entry screen is rather small. All of its bits and peieces could be placed onto one large screen instead.
