It would be useful if there were an option to orient fields other than just top to bottom. Some form questions are related, and short, and it would be a much better use of real estate if they could be grouped left-to-right. I imagine that this could be achieved by sub-sections, or sort orders that support subordinate values, where the secondary value would sort them from the left.
Another option might be to support a tabular format in which questions could be arranged - this would certainly do a better job of mimicking hard copy forms.
Admittedly, this might lead to issues with responsive display formats, but it could save a lot of scrolling for long forms.
