I would like the opposite: with the new interface there always seems to be a scrollbar. I would like this to be Hidden. Reason: when you navigate through an interactive PDF, you would like the readers to use only the buttons. The user should not be seduced to using the scrollbar because the focus on the interactive objects would be gone then. When jumping from page1 to 10 you should only be challenged to do that by using the buttons and hyperlinks. And this is when working in MsWindows.
