I looked at the Day-Night cycle just for a change and find the setting of 4 a bit light.
Examining the range of brightness available personally find a 6 quite satisfactory using 102.1.
Considering that the inspection tool has complete square highlight looking towards 103 or later I wondered if it was possible to make the night darker.
Maybe doing it by adding Night as Dark As to simuconfig.tab where individuals could specify the setting
