LinearMouse supports per-device settings.
You can apply different settings to your mice and trackpads.
If you are uncomfortable with the natural scrolling when using a mouse, LinearMouse can help you reverse the scrolling direction.
As each device can be configured independently, there is no need to be concerned about the trackpad's scrolling direction being affected.
LinearMouse allows you to find a comfortable pointer acceleration and speed and helps you to move the pointer faster and more accurately.
You can even disable pointer acceleration if you are a gamer or designer to get the best pointer accuracy.
