Source: Rocket Note – Chrome Web Store

Geez, I don’t mean to be on a Chrome extensions kick, but here we are. Rocket Note is a Chrome extension that lets you take limited, time-stamped notes on Youtube videos. Unfortunately, there isn’t a way to export or share your notes, but it does come in handy when you’re learning from a Youtube video. The time stamped notes are also links to the point in the video where you created the note, so for longer videos, it makes it a pretty nice way to bookmark particular sections of a video.
