How to Add a Folder to a Homescreen on the Google Experience Launcher

I just installed the Google Experience Launcher on my Galaxy Note 3.  I could figure everything out like how to add new pages (by dragging an existing icon to the right), but couldn't figure out how to add a new folder.  I tried looking in settings, blah blah.. but didn't find any help or online either.  So I tried a couple of things, and finally it came to me to try just dropping one icon on top of another icon.  Boom!  It made a folder.  In fact it made a folder called "Unnamed Folder"  so if you tap on that "unnamed folder" text, it allows you to edit it.
