Why is the tracking axis locked for track to actuator?

The main reason I am asking is because almost all modern games have smoke textures that can rotate about the tracking axis to allow for better looking smoke instead of no rotation where the duplicated texture becomes very easy to spot. Is there a proper reason for this? I know this can be achieved through python but I’m wondering why the logic bricks don’t allow for it.

Thanks

Usually you do not use the trackto actuator. It is more efficient to use the according material settings e.g. Halo or billboard.

Regardless the tracking axis on these materials is also locked. If there isn’t any option to change this where can I submit it as a feature request?
