title: Windows transitions
body: <p>I am developing an iOS app using Appcelerator and I got a quick question.
  How can I choose the transition animation when opening a new window? I do not
  want to use the default slide to right.</p>
  
  <p>This is my code that I use (single context).</p>
  
  <pre><code>tab['tab1'].open(Window.Contacts());
  </code></pre>
  
  <p>This works in a way, but I would like it to open in the current tab.</p>
  
  <pre><code>Window.ContactsAvatars().open({transition:Titanium.UI.iPhone.AnimationStyle.FLIP_FROM_LEFT});
  </code></pre>
  
  <p>Thankful for all input!</p>
