This is good, but how do I add multiple lessons? I don't see how to do it. It's not very user friendly.

Unfortunately, you can't. Highbrow is a one-course at a time deal. We want you to form a good daily habit and not tire yourself out at the same time. Thus, you can subscribe to only one course at a time and take all the courses one by one.

This. I'd love to subscribe to more than one lesson at a time.
