This is my current (as of 4/30/2020) Yabai and skhdrc config as well as the Ubersicht (http://tracesof.net/uebersicht/) widget I use rather than the Yabai status bar. I went this route rather than the built-in status bar because I didn't like how Yabai as of 2.0.1 handled multiple monitors in the status bar.
Nothing is too far from defaults here, and the spaces.coffee was something I found linked in an issue on Yabai's github page.
