What is the simplest method to write a file with Chrome file interface?
<p>Chrome implements the file interface as described here <a href="http://www.html5rocks.com/en/tutorials/file/filesystem/" rel="nofollow">http://www.html5rocks.com/en/tutorials/file/filesystem/</a>, just adding the <code>webkit</code> prefix. The documentation covers several aspects of the interface, but what are the simplest steps, for example, to prompt the user with a file saving dialog, or to tell him that the file has been saved somewhere? For example, let's say we want to save some text data for the user.</p>

<p>I'm mainly referring to lines of code as a metric of simplicity, but within the 80 characters per line (and common sense). I'm also referring to Chrome 26.</p>
