I think you're missing a trick. Genuinely chrome-less could be pretty useful, and more attractive.

The small black navigation bar at the top of the screen could be done away with, if you change your URL structure to be more easily understood & manipulated.

From shoulder surfing various people of various levels of tech experience, i've noticed they are quite happy to edit a logically structured url in the address bar to navigate where they want to go quickly. For example, if the site doesn't provide an easy "up one level" ability.
