It would be awesome to be able to track activity on videos. For example, it would be so helpful to tag users at specific points in a video, or if they start or complete a video. And have all of the stats available to see for the videos with heat maps, average watch times, etc.

Also adding a lot of awesome features that Vidalytics has (https://www.vidalytics.com) such as play gates, resume play, exit messages, and interactive videos.
