I would love to see another tab for “key points”. Instead of scrolling through the textbooks to re-read keypoints, there could be another tab on the side for accessing “key points”.
Example:
To access the key points, the student will need to complete the chapter (the remaining chapters will be greyed out).
After completing all the textbooks, the key points can remain accessible for chapters.
I think it’s nice to have something to quickly reference it.
