I have found that using the back button normally wipes out whatever I was doing and am training myself NOT to use it. For example, if I am editing a program on my desktop browser it uses some popup/lightbox feature for times. If I change my mind and dont want to edit the time there is no cancel button. I instinctively hit the back button and all my changes are erased.

That’s good to know. It’s also not intuitive. Perhaps adding a small home icon into the status bar would help.–though A home icon in the top bar makes more sense.
