Edit: for anyone who doesn't quite read shell expansion, it looks like this:
~
+ Projects
+ My Company Name
+ Clients
+ Client 1
+ Project Foo
+ Client 2
+ Project Bar
+ Internal
+ Project BazFYI the {} is shell expansion braces (which split on the comma), I've edited my comment with a literal tree of how it looks
Edit dos: and I see that you probably knew that!
