I have a suggestion for Lights/Fixtures:
An idea struck me, while creating custom rear lights design for milionth time, as follows:
Have RMB (right mouse button) act as eyedropper tool and scroll mouse button (third mouse button) act as a reset.
This way, one could select a prefered lens/fixture color and drop it with right click.
If error was made, simple third mouse button click would revert it into default state.¨
For the time being, a small update could simply change how the RMB/MMB behaves.
