The idea is to remove everything but the "HOME" link from the topnav bar on very narrow devices, so that it doesn't look cramped. Right now we don't have a ton of stuff in topnav, and losing the tutorial link is annoying. If we want to restore this feature, we should also add a link to the tutorial in the body of the page.
