title: Xcode remember what folders were collapsed / opened
body: <p>I have a big iOS-project with many folders / groups. When I quit and restart Xcode, all folders in the <em>Project Navigator</em> are shown expanded, so I have to collapse most of them manually.</p>
  
  <p>Is it possible to save the state of the <em>Project Navigator</em>, so that when Xcode restarts the same folders are collapsed / expanded as before?</p>
