Not sure when this "update" occurred, I was happily creating my invoices without the need for the columns Quantity and Rate columns. Is there a reason why I am now being forced to use these columns - which do make the screen wider and cause unecessary left and right scrolling - and confusion!!

I note from your previous answers  that there is no option to remove them after the update. Updates are usually made to software to make it easier for the user. Just not sure why you would implement this change reducing the flexibility of your software. Please allow me the option to go back to the way things were.
