I don't found events which would translate scroll/rotate/pinch/move-triggers to equivalent scroll/rotate/pinch/move-events.
As example, allowing to translate an trigger-event like: Trigger: Pinch In → Event: CMD+MouseScrollUp for specific applications would increase the possibilitys and usability in applications on a trackpad/magic-mouse enormous.
Other example: Trigger: Rotate Left → Event: CMD+MouseMoveLeft
The difficulty for the development I think could be to catch and transfer/translate the movement-force/energy of one event to another. But I really hope this could be possible, because allow almost infinite new awesome possibilitys.
