Since we are upstreaming this change, I think it'd be best to just add a new
temporary button in the status area view :-)
But if we are indeed going to hijack one of the status area buttons, then it's
better to hijack the window-switcher button than this, since we do not fully
support multiple windows at the moment anyway.
