Prime Video SubStyler : customize subtitles

If I could select a locally installed and/or a google font instead of a font family or a font type, it would be totally awesome!

Very good and useful extension if you like or need subtitles when watching Prime Video, with more customization options than what Amazon is offering. Works perfectly. Maybe an option to increase the outline's border width could be added? Thanks to the developer for making and sharing it, you rock !
