Motion checking tool.
Now you can be sure that what you see in the user interface accurately describes the situation, observe changes in acceleration and speed of your curves and objects without guessing.
monitor amount of force of movement by acceleration vector
check you character\aircraft\motorcycle tilt by countergravity vector
create correct freefall acceleration by minimising countergravity vector
check speed
upcoming updates: relative speed, guide "physics for animatiors", per object movement data, baking values (for example: to control wind(speed) or engine torque(acceleration) sounds)
