Open folder in new window

I usually open folders in the same window, but occasionally it's useful to have them opened in new windows.

It might be intuitive to right-click on the folder.
Nope, no such option.

In fact, simply hit Ctrl when opening the folder and it will open in its own window.

As a bonus, hitting Shift will allow you to explore the folder in its own window.
