All theme properties

What properties can manifest.json use?

I’m looking for the full list of all theming options.

Nobody has a link even?
Maybe Mozilla failed to provide proper detail.

There is this that’s linked from Firefox Color. As for any other customization, perhaps someone else knows.

is that everything?
I was looking for an MSDN type listing with detail.

I honestly don’t know. I’m hoping someone who might know for sure will be able to answer.
