Hi Mike.
Yup, Oil Slick is a very fitting name for my defaults!

The script that i did is based on the LightingOptions.htm, so you are absolutely right in merging it back to it.
Your modified file also works in V2.52 as the original file is the same for both versions. I don't have anything older installed so i cant check if it can be used with it.

It would be nice to have an option to add a new theme or edit an existing directly from this ui. That would require a major change, as we will have to move the presets into moi.ini. Maybe during the first time it is run.

It might be possible using setOption/getOption and loading/saving the data using JSON, but i'll need to check it in more detail.

Thanks to everyone for their feedback!
