There are many challenges with supporting continuous scrolling between pages. For example, a note can contain pages with infinite size (the default background type), which can be scrolled infinitely within the same page (so you’d never get to the next page). Infinite backgrounds can also be mixed with fixed size backgrounds (including PDFs). There isn’t really a good way to support scrolling through pages in this way. If you have any suggestions, please let us know in the comments!Abram Demski commented
A document with continuous scrolling enabled could disallow any features which mess it up -- specifically, infinite pages.
For me, I find that continuous scrolling is just more "natural" in a number of ways.
1. I don't want to use infinite pages. While they are very appealing for taking the notes in the first place, they are not very appealing for sharing them.
2. With continuous scrolling, I can still see the context of what I was writing on the previous page, when I am just starting the new page. This means less interruption in thinking.
3. I find that in apps which allow continuous scrolling between pages, I feel more comfortable because I can more naturally position the page so that I'm writing in the position which is most comfortable for me -- I don't have to write on the full range from the top to the bottom of the tablet.
