Viewing shex.io in a browser in Desktop mode, I can navigate to Print mode, and from there to Mobile mode, and (usually) from Mobile back to Print, but I cannot navigate from Mobile or Print back to Desktop.
I tested this in OSX (Chrome, Safari, Firefox) and Linux (Chrome and Firefox).
If anyone wants to own this, that'd be great. I stole most of the markup and CSS (indirectly) from the W3C homepage. If anyone's up for debugging shex.io, they can use the W3C homepage as a template.
