The Lighting Controller

Hi Guys,
well once again i am having this problem in the 3d visualiser this time with the truss not staying in position, if you remember i reported the same problem with instruments not staying where they were put a while back (in which i had no reply at all from support.)

Would it be possible to put into 3d a save button to lock in the settings when you have set your stage, can't understand why there isn't one.

Each 3D object position change in 3DView is supposed to be saved in real time.
If possible, please post a video showing the problem.
