Page limit marker lines would allow to see how an infinite note would be printed
I can draw the note in the unlimited size "paper" field.
If I want to see that note, I can zoom it in and out as I see fit.
But when I will print it, my note might be too large (and printed on separate pages) or too small for the printer page.
Many editors might show you the projected printer page limits on your screen to allow you to arrange your text/items with future printing in view.
It would be nice if Papyrus would also let user know how exactly his note will be cut into printed pages.

A page layout that has letter size (regular) paper to make it easy to print. But instead of having to click 'new page' button, it lets you scroll vertically forever while still separating the different pages with a bold line. Similar to how you can view PDF documents. This is a much faster way of writing notes for University while still being able to easily print the notebook pages as you would if it were just regular letter size paper. I hope this makes sense! It would be a very useful layout, and easier for quick viewing of notes.
