^ I don't think you need this

Done.

it's arguable that you should be using `document.documentElement` instead

[benwells, 2013/03/20 07:49:32]

I was using body as I didn't know how to add a style to the document in the
html. Now I don't need to :)

this could be reduced to

  document.documentElement.toggleClass(
      'launcher-layout', defaults.launcherFeedback);

[benwells, 2013/03/20 07:49:32]

That didn't seem to work. Do we have our own toggleClass thing (googling shows
it as a jQuery thing).

[Dan Beam, 2013/03/21 01:09:11]

sorry, meant document.documentElement.classList.toggle()
