No better way than polling? Are there no events we can listen to instead?

[jdufault, 2016/03/03 23:11:04]

There is OobeScreenWaiter on the C++ side but nothing I could find on the JS
side.

What do you think of firing an event here[1] so that it can be listened to with
something with something like

    Oobe.addEventListener('onscreenchanged', function(screen) { ... });

Not 100% sure that will work since I haven't tested it, but I think it should.

Let's do it. Maybe Pavel has a better idea?

[jdufault, 2016/03/04 20:42:47]

Done.
