If you have a git repo for anything that's supposed to be an interface to anything, please put one screenshot at the top of your readme. I get that the website has these, but its the best way to let me know more about your product in one shot.

Agreed. With a multi tab/page interface system like this, it would be nice to see a slideshow of different useful pages and nice data vis metrics.

As an aside, GitHub made a change a while back where videos and gifs don't auto play without the user clicking play first. Boo.
