title: good clean interface library to complement jquery.js and backbone.js?
body: <p><em><strong>I plan to build a facebook instant messenger clone,  and look for a jquery interface framework 
  what I aim to so is:</em></strong></p>
  
  <p><a href="http://www.arrowchat.com/demo.branded/" rel="nofollow">http://www.arrowchat.com/demo.branded/</a></p>
  
  <p>Now the idea is to have a clean user interface library to handle the dialogs and other stuff..
  I already looked at:</p>
  
  <ul>
  <li>ember to complicated pre-mature for now</li>
  <li>backbone but does not support ui stuff</li>
  <li>jquery-ui distaste on this one not sure why, its to bloated for starters</li>
  <li><a href="http://www.jeasyui.com/demo/index.php" rel="nofollow">http://www.jeasyui.com/demo/index.php</a> seems nice but not very tied to backbone.js - this is perfect but need lib thats more dedicated to backbone.js</li>
  </ul>
  
  <p>Are there any other jquery library's to render user interfaces perhaps specific to backbone.js to get a decent layout up and running on clean code? thx!</p>
