Smart Fixed Navigation

With the CodyHouse team we have been spending some time thinking about how to make the back-to-top button "smart". If the goal of the user is to get back to the navigation, why don't put the navigation where the back-to-top button is supposed to be.

We come up with a new interesting UX solution, that can be downloaded for free on Cody.

Here is the demo:

Finally we created this animation (kudos to @Gabriele Mellera) to show the idea behind this code snippet.
