title: AEM CRXDE Query widget customization
body: <p>I need to customize the query widget in CRXDE (the one from Tools -> Query). Specifically I need to be able to add a new button to save queries into some sort of favorites as well as to load them. 
  And a second button in search result widget to export the results into a excel file.
  Any idea what nodes/templates are related to each widget?</p>
