This software lets me change the function of buttons and so forth, but doesn't let me change the scrolling increment for the wheel. I can change it in the Windows mouse settings, but a user should not have to go to two different places for mouse settings.

There should be better control of panning with the middle button. Currently, clicking it causes a symbol that's the vertical equivalent of <-.-> to appear. It should be <---.--> vertically, with the speed changing depending on the distance from the center. Currently, it's very hard to control the speed.
