I tried the "." for the working directory, but it didn't work when I was playing around with it. Operator error, I guess, since it now appears to work fine, as you suggest. I did want the folders, so that makes the /e switch necessary. Starting to get more typing, so I made it a script. Probably overkill.
"Folders" is one of the buttons you can add to the toolbar if it's not there by default. It allows you to toggle between the view with the folder tree and the view without the folder tree. Very useful.
