[Feature Request] Pre-load the next lesson content

I would love to have the next lesson begin loading before I’m finished with the present one. Waiting in between lessons to download voice and video clips is fine, but if I understand right, it’s better yet to go as fast as the student reasonably can.

A downside to this feature would be that an “extra” lesson gets downloaded while doing the last one. Also, for students that like to choose the lesson rather than go along with the app’s automatic choices, it might not work as well. Maybe this would be an optional feature?

Edit: never mind! I guess you can download the content for offline use.
