Being able to see what the students will see will be helpful for navigating.
I want to be able to see the notebook as viewed by a particular student, rather than see all the content as a teacher. This is a standard function of platforms such as Moodle, it allows you to check what you have created without the distraction of the teacher functionality.

Student view of assignments is already available by clicking the 3 dots on upper right. Is this what you are referring to?
