For working on Lighting Config classes, it would be incredibly beneficial to see using the DayZ Diag Exe, the Lighting Class that is currently working.
This would be particularly useful when working on a map with custom lighting, or even any underground areas that you may add to the map. This especially could be incredibly useful when mapping out certain zones.

For myself, it would be incredible to see the Lighting Config that is currently on depending on time of the server with all the stats for each section in the lighting config such as "Diffuse, DiffuseCloud" etc.
Being able to see the stats and which class is currently on would be incredibly beneficial to trouble shooting without constantly going in and out and messing with numbers hoping that changes the correct class which wastes a lot of time.

This could be activated as a separate option in the "Weather&Environment" tab as a suggestion.

Here is a proof of concept that I quickly whipped up.

Thanks for reading.
