[Bf-funboard] Blender Lights

[Roger]

In Blender 2.5 can we have a light switch.
So that individual lights can be switched of or on at will.
When switched off the wire mesh turns light grey.


I usually have 2,3,4 cameras in a scene to check renderings from various angles 
and altitudes.
It would be great also if cameras could be turned off and on also.
Only the switched on camera renders without the need to select the camera 
then<CTRL 0> to render that view.
TIA
