Whoops, didn't mean to leave this in. Strike it from the record!

optional: Maybe just NewWindow() so the reader doesn't worry about what the
nullptr is?

Also, just to double-check, does the window need its visibility set / to be
shown?

[sky, 2016/05/06 22:12:57]

Done.
No. Widgets should be hidden initially until shown.
