When listing items in the books side of Inventory Manager, the quantity in stock of that item will be displayed if you have any, but recent or lifetime sales of that item would be even more useful. If you could see that you have 20 in stock of an item, and it's sold quite a bit, you're more likely to list it than if it hasn't sold before. Right now, to find this out, you have to access different parts of the software or reporting.
