this is just the most minimal shell to toggle fullscreen from a chrome packaged app.
a "boilerplate packaged app" if you will.
you want to build a full-screen desktop application. start here.
it's just a simple empty window ...
... but the button will toggle you in and out of full screen. which is where you want to be.
USAGE: (Chrome)
* Download this code into a local folder (either zip or git clone)
* Enter chrome://extensions into the URL bar
* Click the "Load Unpacked Extension" button and select the local folder
* Click the "Launch" link for this new extension
(after "getting to first-base" you might to start throwing objects and widgets into your "base" using the <webview> tag ... it's like an iframe but is a complete, top-level, non-bustable browser instance.
... try http://github.com/figital/base)
