I am one of those people, because I see the examples and the text box but nothing appears to occur when I use it or try any of the examples. Tried Chrome and FF (and disabling extensions), so I thought I was just doing it wrong. However, I did a little more digging because of the discussions, and I think the button that I am supposed to click is hidden http://i.imgur.com/kI8TrfE.png http://i.imgur.com/kI8TrfE.png I dont know how this is happening across both browsers though, but I thought I would leave this here if anyone else is confused as I was. Update: After trying a few things, stretching the screen width made the button pop up.
