Let's say you have a note with a lot of pages and you want to print them. Most users use for handwriting a page type with lines or squares. But if you want to print the note out, the squares and lines are only good for draining your ink empty.
So I would suggest to add the feature to the "export to pdf" dialogue where you should be able to select: "different page type - blank" aso.

As I use papyrus in my physic studies (lectures at university) for ALL written notes (>20 pages per day), I suggest under the motto "Back to Basics" very simple features that would make work easier.
The features are (in my opinion) very important for using papyrus as a simple college block and especially for those people who use papyrus every day and excessive (like me: 3 hours+ every day).
