| Hi Dinos! 
Thanks to your script idea, I took the LightingOptions.htm UI script for V3 and basically merged your Themes script into it!
 
So, I was curious to see if this could be done. Having the ability to choose from good presets and being able to simultaneous tweak the finer details was a plus.
 
By the way, I renamed your "Default" to "Oil Slick" (I like it!) and added MoI's default for "Default".
   
Download the zip file:
LightingOptions(Themes_V3).zip 
You'll find "LightingOptions.htm". 
Copy this over the original file in the MoI 3 Beta.../UI folder and you'll have this new feature integrated into your MoI Options. 
Please remember to backup you original "LightingOptions.htm" file!
 
To bring this dialog up by itself - add this script to your keyboard shortcuts:
   script: /* Opens Lighting Options Dialog */ moi.ui.createDialog( 'moi://ui/LightingOptions.htm' );
--This is for the V3 Beta version only-- |
