This is not so much a feature as something I have noticed when printing out the forms - they don't seem to utilize the full page properly. I made a short quiz that, if I was able to edit it, would definitely fit on one side of the paper and not spill over onto the backside. I looked back at other forms and it seems to be the case across the board that the portrait-orientation of the form seems to only use the top two-thirds of the paper and that seems like a waste to me.
I don't want to be able to manually edit this (tedious) but it seems like this is a waste of paper. Is this due to the scanning algorithm? Or just has no one else noticed this before?
