At the moment if I am in the vertical scrolling and I have in my exercise book pages with different sizes, like A5, A4 and A4 rotated, the maximum scrolling edge in horizontal is big as the biggest page in the hole document. So if I am writing on a A5 paper (because image was A5) GoodNotes let me scroll further than the page size. Also if I import an image and this is not perfect in A4 format it would be helpful and nice, if I could resize it to A4 for example.
