video structure on Udemy

[mwrr]

I signed up for a course, a series of videos, on Udemy. Aside from the value of the course, I'm stuck by the method of delivery of a series of videos. On the right of the browser window is a vertical list of videos that automatically progresses down the list as you watch them, and keeps track of the ones you've watched (see attached screenshot). Does anyone now how to accomplish this outside of Udemy?
