title: Editor tab disappeared in GUI
body: <p>The MATLAB GUI normally (for me) has 4 tabs in the upper left - Home, Plots, Apps and (I think) Editor. However the editor tab has disappeared and I cannot find documentation how to turn it back on. I tried the Layout->Default but that just arranges all the visible windows and doesn't re-enable to missing editor. </p>
  
  <p>Does anyone know how to turn this back on?</p>
