Idea - Bookmarks in Regular Practice

Hello!

When I am working through the Social Science and Literature timed questions in the SAT Practice, it helps to use the bookmarks so that I know which questions I need to review. In the sections that are not timed, I would appreciate if they also had bookmarks. Even when Khan Academy isn't officially timing my work, I try to time myself to make sure that I am not spending a prolonged length of time on a specific section.

Thank you!
