title: Where to add Global variables in ExtJS MVC?
body: <p>I am wondering where to add global variables for an ExtJS Application. I already looked at some suggestions in stackoverflow that mention that you can add them inside app.js. But, can anyone be more specific? My app.js looks something like this:</p>
  
  <pre><code>Ext.application({
  
      launch: function() {..}
  
  });
  </code></pre>
  
  <p>So, where exactly do the variables go? In the launch function? Outside <code>Ext.application</code>?</p>
