Suggestion: Allowing control of the mouse location to create your own tether, or create a bounding box (ie: the map). This would allow fast paced games to keep the mouse within the map, and not click outside of it. An example would be a game I recently did:
It could also be useful in other scenarios as dragging something across the map, it would allow the dragged object to stay within the bounds of the map, or bounds of the window.
