Bookmarks - It would be nice to be able to bookmark content of the material in the classroom and possible take notes and elaborate on it. These notes will automatically be transferred to your NXU locker. Suggestions : While going through the material, it would be nice to be able to suggest a correction, another material that explains the concept better etc at the click of a button. These suggestions will be sent to the professor, course creator and/or any other person it is relevant to. If the suggestion is approved, the corrections/auditions can be sent to all current or past learners or automatically be implemented for incoming learners of that particular course. Flags: Even if you do not want to make a suggestion or correction. You can flag an error you notice in the course so that changes can be made.
