Is this possible?

It would be so much easier to scroll along a 3200 pixel wide screen than to move from one 800 pixel-screen to the next and to the next. It would then also be possible to move only as far as your next widget or shortcut, i.e. stop halfway between screen 1 and screen 2.

I am a complete noob re Maemo but why are there 4 screens, and why not 1 very long one?
