Ah, yes, I had forgotten that I didn't test in anything other than Firefox. I'm very much not a web developer--working with JS is really quite a pain, and I had to use as much ES6 magic as possible to make it tolerable. Looking now into Traceur to de-ES6ify the code...

OK, so it's fixed now. Tested in Firefox, Chrome, and Safari. As soon as rawgit refreshes its copy, the new version will be live.

It's fun :)
