I really like Buttonizer so far but one issue I'm having is on a mobile browser or tablet. When a user start scrolling the address bar will automatically hide on most devices to free up for space. However when this happens the buttons awkwardly shift since it's recalculating the size of the screen. So when your scrolling up and down anytime you change direction they jump. How can this be fixed so I can set my button position in the same spot regardless if the address bar is showing or not?
