EXTJS - Way to get a reference to the viewport from any controller

An easy way to get a reference to the viewport from any controller

Here's an easy way to get a reference to your viewport from any controller:
Ext.application({

  launch: function(){

    this.viewport = Ext.ComponentQuery.query('viewport')[0];


    this.centerRegion = this.viewport.down('[region=center]');

  }

});
then, inside say, a controller, you can call this:

this.application.viewport

to get a reference to the viewport.
