Use the Benefits & Features tab on the Item screen to create a list of features and benefits that can be easily accessed by sales people when working with customers.  Features might include BTUs or number of jets while benefits might be tax savings or improved health.  The Benefits/Features button on the Inventory Tab of the Main Menu will only be active if there are benefits and features available for viewing.

To add Benefits & Features to an item, double click the item or highlight it and click Edit Item.  Go to the Benefits/Features menu and enter the desired text.
