Hi Lorna

You *blow me away* with these tips! I'd never heard of this command so I couldn't wait to give it a try. It doesn't work on a Mac by default, but I quickly found this blog post with some super easy instructions on how to install and get it working: http://shaunchapmanblog.com/post/329270449/how-to-install-the-tree-command-on-mac-os-x

I'll definitely use this command a lot going forward. Thanks!
