Customize Plugin possible?

I’d like to get some help on customizing this awesome plugin.

In concrete, I need to make the “bgcolor line width” the same width that the “fgcolor line width”.

THIS kind of circle is what I pretend to get.

Could you please tell me what must I change, and where in the Plugin Editor can I change this?

Thanks for your support.
Regards!
