Overriding style_options.yml

I was going to say the same thing. Wouldn't it be better to put only one of them? It is a bit confusing that by default there are two in the same package.

And as @stevieegee suggests to put one os these files only as an example, like example.mercury_editor.style_options.yml

And thanks for this awesome module!

It is not currently possible to override the definitions in style_options but you can override the context by putting your own style_options file in the theme. This is a current limitation of the style_options module and not mercury_editor specific. We are in the process of removing style_options from mercury_editor in an effort to be less opinionated.
