Can you change that browser address bar effect while scrolling?

Now, when you crolling down, it's shrings "zoom out", so when you scrolling up again -> Can you make it to "zoom in". Now it's kind of rises and its not sweet with the other effect.

Other thing.. When you scroll up or down, corner gets an arrow. Only problem is, that little arrow is whole screen wide.. bug? This is annoying when you use phone in landscape and i hit that area all the time.

Love your browser and hope you can make it even better =)
