idea = use both wheels at a time for a different function.
example = in powerpoint or acrobat reader, thumb wheel is scrolling left n right. So, people can scroll vertical n horizontal & with idea they can zoom in also. This is an essential feature during meeting presentation. This might be not easy for people to adopt, but 3D cad designers like me are already using multiple mouse buttons at time for improved productivity.... So we should give a change to this idea may be in beta release....
