title: ExtJs UI Designer tool
body: <p>Is there a designer tool for ExtJs or Eclipse plugin for it?
  I'm developing an interface which is completely similar to desktop environment.</p>

  <p>Now I'm modifying the above demo. But it is very hard and time consuming process.
  Can somebody tell me about this?</p>
  
  <p>Thank you!</p>
