Printable Page Layout
Windows journal has a very good page interface that would be nice to see available in OneNote. This feature/option to have a multiple "scroll-able" smart page layout like journal or word would be preferable in many instances. (i.e. doing homework which may have to be printed for submission).
It's also nice to have access to those pages with out having to set up a separate page within the notebook. When I want to go and print either to printer or PDF, it would be nice if I didn't cross my imaginary margin and end up with half a word or sentence on a completely random page when I go to print. Page layouts like Journal and word give a tangible boundary, but OneNote has superior inking and organizational features.
Some sort of a (very) basic drafting interface would make an awesome addin for many Engineering students needing quick sketches in their notes. i.e. compass, polygon, basic 3d cube, pyramid, trim tools and shapes.
