title: Eclipse: automatic file opener plugin
body: <p>I'm searching this feature (or plugin) in eclipse:</p>
  
  <p>a prospective "project oriented" that remembers opened files, and when I open/switch another project eclipse closes all file of the last project selected and open files previously opened of the new project selected</p>
  
  <p>use case:</p>
  
  <ul>
  <li>I select Project1 -> [eclipse closes all file actually opened]</li>
  <li>I double-click on file1 in Project1 -> [eclipse opens this file]</li>
  <li>I select Project2 -> [eclipse closes file1]</li>
  <li>I double-click on file2 in Project2  -> [eclipse opens this file]</li>
  <li>I select Project1 (again) -> [eclipse closes file2 and opens file1]</li>
  </ul>
  
  <p>there is something like that??</p>
  
  <p>thx in advance</p>
  
  <p>p.s. i'm sorry for my english -.-'</p>
