Apply Custom CSS

[VidFerris]

Would be nice to be able to custom-set the page CSS in the options window - external custom stylesheet addons like Stylus can't work for it because WebExtensions can't modify each others' pages. (As an aside, thanks for making this - really great tool!)

That definitely sounds like something that would improve the extension! Would you be interested in writing a PR for it?

Sure, I'll look into it over the next few weeks. Haven't worked on extensions before so it'll be a good way to learn!
