I like the new buttons. It would be great if you could include a "Toggle-button" and an "Home-button" as well. Using an image for toggle works, but it be easier and better looking with a button included for a interactive view. Also, Home button for going to the FrontPage and not only previous page is handy. Eventually rotation on the Back-Button
I need the Home button too! I have created a complex DrillThru structure with 12 DrillThru pages. The Users can only go Back one page at a time though. I want to give them a Home button that they could jump back to the main calling page
I posted another idea for a Hamburger button. Sorry for the overlap :(

And a "Filter-button" please.
