A few times I've wished this feature was present. I have huge projects with many folders and the files can number in the thousands, sometimes with the same names but in different folders (i.e index.php).
At times I'd like to go to the folder in the drawer that a currently opened file is from (to open another related file for instance) but that folder and file may exist several layers deep in another folder that is now closed.
It would be nice to have a command (either from menu or right clickable menu) that will open the folder hierarchy to expose the folder and file list.
Thanks, Ed
