It would be really nice to be able to scale the our whole avatar with a global scale slider so we can be really big or really small without changing our shape valaues, Idealy this would act much the same as the hover height slider.
This would also increase or decrease this scale of hitbox to match the new scale.
Additinally it would be great to have a LSL function to control it like llSetAgentScale(float scale_value); or something to that effect that sets the scale of the owner of the object. If a permissions request is required I would be fine with that as well.
