title: Does CompositeWPF support multiple windows/shells?
body: <p>I'm looking at using CompositeWPF (<a href="http://www.codeplex.com/CompositeWPF" rel="nofollow noreferrer">http://www.codeplex.com/CompositeWPF</a>) - aka Prism, to build an application I am working on.</p>
  
  <p>The application isn't a traditional LOB application, however it does present data and state information to the user.</p>
  
  <p>One thing which I am unsure of is if CompositeWPF supports more than one Window or Shell. I would like to have my application notify users with a border-less window which appears in the lower RHS of the screen (think MSN notification) but still use the idea of views being injected into the region etc.</p>
  
  <p>In addition to this I would like to be able to react to a user action (e.g. double click on something), hide the main window and present a progress dialog while work is being performed.</p>
  
  <p>So, is this possible?</p>
