in the 9.7 silence used in his last last rom when u circled the pad it would scroll up and down like the up and down buttons, it was quite annoying. i enjoy using it as the zoom cuz when i double tap to quick zoom sometimes the text is either too large or too small and it allows for a quick adjustment, i never got used to that zoom bar so that being said, i cast my vote against 9.7 (unless somehow u can magically make it zoom when circled
then u will be the kottonmouth king of all)
