title: Android studio does not show strings preview
body: <p>I'm running Android Studio on Mac OS X and I'm not able to see the hard-coded strings values in the editor as well as I cannot see drawables preview. Anyway, I can see colour preview in the xml file. Is there any option that I need to turn on?</p>
  
  <p>I know that this may be due to a bug, but they've strongly publicized this feature so IMHO it works!</p>
