I wanted to make a second comment about this: I would like for my students to be able to download a pdf of the notes as well.

I am a professor and I use goodnotes to lecture from my ipad. I would love to be able to share these notes with students via a read-only link! By the way, competing apps, like notability, do have this feature.

I would love the ability to share my notes with others, but in a read-only manner.
