title: How to access extjs controllers from console
body: <p>It'd be super useful if I could access instances of my views and controllers in my ext.js application from Chrome's console. Does anyone have a clue how to do this?</p>
  
  <hr>
  
  <p><em>coffeescript:</em></p>
  
  <pre><code>window.cms = Ext.create 'Ext.app.Application',
    name: 'CMS'
    controllers: [
      'MyController'
    ...
  </code></pre>
  
  <p>It would seem that <code>cms.getController('MyController')</code> would do what I want, but I get a constructor back instead of the instance I'm looking for.</p>
