Please, add "acceleration" to Magic Mouse settings

Hello everyone. I love BetterTouchTool and it is saving my life with Magic Mouse. I'd really like just one more control: speed acceleration. I have used USB overdrive for over 20 years, and I'd love to be able to control and tweak the Magic Mouse pointer movement even further.

In other words, inside the MaMagicig Mouse settings, right under the "Set mouse speed" slider, I'd love to see a similar slider controlling the mouse pointer acceleration. That'd allow very fine control of the pointer and make BetterTouchTool an even more powerful tool.

Thanks for listening!

All the best,
Fab.
