"Save" & "Cancel" buttons at top of "Edit Invoice" page

A quick suggestion: I think it would be great to have save and cancel buttons at the top of the Edit Invoice form, as well as at the bottom. Nearly of the info that needs to be entered/edited on a regular basis is at or near the top of the form, not the bottom, so it would be very convenient to have save and cancel buttons up there, instead of having to scroll all the way down past the paypal/google info and the customer notes and T&C info just to get to the buttons.

I know a little scrolling is not a big deal, but it looks like there would be plenty of room up top without crowding the page, and it would be handy to have buttons there.

Thanks for your consideration.
