Having the option to enable a sidebar that includes lesson specifcs (for users that are enrolled in a school-assigned classroom and cannot revert to the previous website layout)

I believe that having the option to toggle the sidebar (with lesson specifics, just like how the previous version of this website had it) on and off in the new Khan Academy Classroom layout is extremely beneficial for student users who also use the same Khan Academy accounts for independent studies (but cannot cannot revert to the original website layout because they cannot exit their classrooms). Additionally, I believe that re-adding the sidebar will further facilitate navigation within a Khan Academy course.
