title: Disable Eclipse auto-save of the perspective
body: <p>Currently, every time I move a window, the new position is saved in the perspective.</p>
  
  <p>When I want to restore the perspective (as it was when I saved it), <strong>it doesn't do a thing</strong>, because the perspective was saved with my modifications.</p>
  
  <p>I want to disable this behavior, how can I do that ?</p>
  
  <p>Thanks</p>
