body: <p>How do I unhide a working set in Eclipse?</p>
  
  <p>I'm using Eclipse and I'm trying to organize my projects into working sets. When I was deleting one of my working set folders (by pressing the delete key on the working set), two options appeared: remove or hide. I clicked on hide but now I want to unhide this folder - how can I do that?</p>
