Simply add an option under the "View" menu that allows users to hide the horizontal and vertical scrollbars that frame the working area.
Aside from the obvious benefit of a bigger working area, it would help people who frequently misclick the scrollbars instead of the artboard or options panels, causing the view to jump, which can be very jarring, disorienting and annoying.
The current "solution" of entering fullscreen mode to hide the scrollbars changes too many other things. Most users like having their taskbar while working, for example.
