Invoice template: Unit price shows "-" on real invoices, and a suggestion for zero-value rows

I noticed two things on my invoices and wanted to pass them on.

1. Unit price is missing on real invoices. In the invoice template editor the preview shows the unit price correctly (for example $110.00), but on actual customer invoices the Unit price column shows only "-". Example: invoice INV-4152, "QuickText: 1-Month License", Qty 1, Unit price "-", Amount $20.00. I would expect the unit price to show $20.00 there, like in the preview.

2. Suggestion for zero-value summary rows. Every invoice shows "Discount -$0.00" in red, even when no discount was applied, plus "Credit Applied $0.00" (and "Transaction Fee $0.00" in the template). It might look cleaner to hide these rows when the value is zero, or at least show the discount in the normal text color when it is $0.00. A red line on every invoice can make customers think something was deducted or went wrong.

A small side note: in the editor preview, the Sub Total shows $110.00 although the two sample lines add up to $120.00 ($110.00 + $10.00). It is only sample data, but it made me double-check the real totals.

Thanks!
