We think it would be useful to be able to see the current stock while grabbing an item. This allows you to see if the stock according to the system actually matches the physical stock. As it is now, when you have clicked through in the "pick menu", to see the location of the item, you cannot see the current stock.
Have you tried the inventory during restock function? if so is similar function needed for Picking or is it just see the quantity that should be available?
