We should have the possibility to try to refactor by ourselves.
Maybe show the code to refactor and an editor where we can try. When we're ready we can launch the step by step solution.
(forget about the blue background in some part of the code, I didn't had the courage the remove it)
In the end we can easily compare (as it is right now), but also with our own code.
I did those screens quickly so you get the idea.
At least, we should be able to copy paste the code ('impossible' for now).
Also the popovers... pop overs the code itself.
When you just start the example and you want to get the big picture of the code it's a bit annoying as you can't see the whole code.
You have to go to the next next in the hope it will move away and nothing will change.
Could we see the code before the first popovers appear ?
