Helpful tip for iPad/iPhone users.
If you get bounced to the top of the bread *swipe left to right on screen and it will go back to where you were.
If you get bounced to another bread because of Pb/lb not being labeled, *swipe left to right on screen, let page load and then swipe left to right again. This will take you right back to where you left from. Not sure if it works on droids.
