title: How to make window size observable using knockout
body: <p>Trying to do something about the browser window:</p>
  
  <ol>
  <li>Is it possible to make the window size (<code>$(window).width(), $(window).height()</code>) observable using Knockout?</li>
  <li>How to keep <strong>FUTURE Added Elements</strong> in the center of the window? Is there something can be done using the <strong>jquery live method</strong> or the <strong>knockout custom bindings</strong>?</li>
