Show tax rate/percentage and price excluding vat with free version?

Hello,

I am testing with the plugin if I can get the invoice template what i’m looking for.
I only missing two columns in the section with the products.
Would it be possible to see behind the product also a column with the tax percentage (like 21%) calculated on the item? And would it be possible to see the price without tax?
So that you can see in the product row the columns: price without tax / tax percentage / price including tax ?

Thanks for building this great plugin!
