title: How to open a popup window with an external url in a chrome app? (like window.open with _blank)
body: <p>I need to open an url on a new and single tab chrome window, as you would normally do with window.open and "_blank", but when done inside a chrome app, the url is opened in a new tab of an already running chrome, ignoring all the window features options (width, height, etc).</p>
  
  <p>Are we doing something wrong or is this a chrome app constrain? Any way to solve it?</p>
  
  <p>Best regards
  Sergio</p>
