I love the idea of having file source code next to the tutorial.

However, it doesn't work that well on small mobile display. Perhaps keeping them next to each other, displaying only one and switching between them with right and left swipes would work better?

Yeah, that's a tricky one! We were thinking how to do it correctly and I think we will add a "collapse" function to the code editor on mobile, so you'll be able to collapse / expand it on demand. Would it work for you?
