Featr storyboard

Because our application changed from Rankr to Featr, is seemed useful to reiterate on the storyboard. We developed a new one, (mostly) according to our current version though some minor improvements in the prototype have not been taken into account.

We explicitly started from our prototype. Henceforth, the storyboard is quite detailed and might even seem very cluttered. This is due to the effort to fit everything in the small boxes and still keep it readable (more or less). It does however, give an idea about how to operate our application.
