Scroll down to kill the sticky navigation. Scroll up to bring it back.
There has been a recent pandemic of web designers hell-bent on making web site navigation elements pinned to the screen. All various sorts of navbars, sidebars, toolbars are all seemed to be slowly overtaking the screen real estate leaving nothing to the actual content. It probably doesn't look as atrocious on these giant cinema displays they are probably using but for these of us who do use smaller laptop screens this scourge is truly maddening.
Lo and behold, this is an attempt to purge this curse of the web once and for all. Basically, when you scroll down this extension would look for all these naughty site elements that refuse to be scrolled and mercilessly hides them. Scroll up to bring them back.
It is important to understand that this is a beta version so there might be some quirks to iron out. If this extension does break site navigation use the support tab in chrome store to send me a link to the offending site.
