Spring mode mouse control

[Ian.Burnett]

I didn't see this feature when setting up controls for mouse movement. JoytoKey is free software for PC that has a ton of features and includes spring mode. Spring mode mouse control (making the mouse snap back to center of screen) is very helpful for games like Agar.io. Please add this feature or let me know if I have overlooked it. Pretty disappointed in the lack of features for a paid app.
