title: TitleBar back button for UWP
body: <p>I've seen that the windows settings are using a <a href="https://i.stack.imgur.com/O86ae.png" rel="noreferrer">back button</a> in the title bar; and would like to include something like that in my UAP but since Win10 is pretty new I couldn't find any information if this is achievable in a simple way.</p>
  
  <p>Thanks very much</p>
