How to import assets or just create simple folder

This is surreal…

How the … do you import an assets folder into your project?

As far as I can tell from the docs. One have to set the configuration and add the external folder(s) that way. I have done so and the external folder is listed (and checked) in the “default configuration menu”. However, the folder I have added to the project is not visible in the project window…

Who came up with this idea… Just let me freakin right-click and add a new folder… WTF…
