what i did was what you suggest - include a link to the home page in
the header. you won't get the animation that way, however, and the
whole page will refresh. so it's not ideal.
it's a good feature request though. we could add another annotation,
maybe go_home, which would animate to the left, reset current state
and load the page you specify in href attribute.
go ahead and file a bug here and mark it as enhancement, if you like:
