title: Automatically reveal current file in TextMate project drawer
body: <p>There is a <a href="https://stackoverflow.com/questions/3393334/how-do-i-highlight-the-current-textmate-document-in-the-project-drawer">key chord to highlight the current document in the project drawer</a> but I want it to happen <strong>automatically</strong>.</p>
  
  <p>Is there any way to make TextMate reveal files automatically by expanding the parent hierarchy whenever I switch documents? If possible, I'd also like to collapse that hierarchy to its prior state when the file loses focus.</p>
  
  <p>(For background, as a point of comparison: In Eclipse I can <a href="http://wiki.eclipse.org/FAQ_How_do_I_link_the_Navigator_with_the_currently_active_editor%3F" rel="nofollow noreferrer">link the Navigator with the currently active editor</a> to always show the currently edited file in the hierarchy of files. It does highlight the file if it's visible in the project drawer, but I want it to reveal files hidden in collapsed folders. )</p>
