As with the Black topbar you can simply make it transparent by simply adding a class to it. This style emulates that of the photos app and is epecially nice on sites with a custom background image.

Also available are the well known navigation arrows that you see above. I have decided to give you the option of simply having 1 button at the top or using a "breadcrumb" system with wich you can have multiple left or right arrows on the same page. This is of course for the ease of use of your site enabling the user to naviagte quickly.
