Is there a great tutorial that goes into detail on building a SaaS-style design with the new Responsive Engine that covers off mobile, tablet, and desktop (widescreen) views? Ie Something with a Side menu that collapses down to side icons for tablet, to top and bottom menu for a phone. Imagine FB on the 3 devices.
A lot of tutorials seem to cover building things in one view or the other, but not in building apps that work across devices.
Thanks!
