It would be good to have some more versatile, mathematical or scientific paper templates. For example, a split page (similar to a Cornell note-taking), where one side is ruled and the other is graph paper. Perhaps, a graph section on the top half, and a ruled or blank section underneath where one could add notes or symbolic work. Also, paired with this suggestion is the echo to add math conversion tools, converting to a display equation with LaTeX. This is the only reason I may choose Notability over Good Notes to use to deliver class notes when teaching. Sadly, in almost all other ways, Good Notes is a better tool I think, but the math conversion and edibility tool as an in-app purchase makes Notability more usable for teaching mathematics.
