Video playlist option?

Hello to whoever is reading this

I'm a fellow user that uses Khan Academy and so far, it is a great place to study. The videos are highly informational and easy to understand. But there has been a single gadget or a tool that has been missing from this site, and that is a way to save a video into a personal playlist of education.

I am aware that you have videos on Youtube where the learners are able to create playlists, but switching from the official Khan Academy site and the youtube video tab really is an easy way to get students out of their studying zone. 

Even tho it seems like a minor feature, I believe it would become more helpful for people to study off this site. Thank you for taking the time to read this.
