+This is a proof of concept for presenting "modules"/sections from multiple YouTube videos as a method of learning a topic. Easy navigability is a focus here: You can use arrow keys as well as vim bindings (`hjkl`) to navigate within and across modules. `shift` + arrow keys/`hl` do larger jumps within the content. Additionally, `m` to toggle mute and `;` to wind back five seconds and continue playing.

 A lot of the time the best way to learn is to work on a project that uses the skill you want to learn. When you get stuck, just Google your way out of it or go to the relevant part of the documentation.

 Some podcasts provide helpful metadata for navigating to the parts you're interested in. Then there's always the handy fast-forward button. Wouldn't it be nicer if you could 
 
 1) check the boxes of the topics you're interested in and have those queued up?
 2) store the "want to listen" items that you don't yet have the requisite knowledge to understand?
 3) have a standardized, centralized list of topics you a) are interested in and b) understand?
