What does this XIM App do?
I looked everywhere and can't find a description.
That's my fault. I wanted to post the app since many people were asking for it, but I didn't have time to write a description.
The app is similar to the smart advanced settings, but with much more control. It lets you edit the way your mouse responds to different velocities. You can simulate having acceleration by editing the app's curve to resemble a parabola, or simulate boost by keeping a straight line and pushing the first point above 0.
I will work more on it this weekend and post a new version along with a better description (and a screenshot or two

)
