I want it because I'm a visual person and I like to see all the details on the screen while I'm working. I don't print invoices anymore; it's all handled electronically. So I don't want to have to print or do a print preview to see the invoice subtotal. And I don't want to manually add up the line items either. It just doesn't make any sense to me why this wouldn't be a default in QB. In fact, the option is there . . . it's just not been made available, for reasons that I can only guess at.
