Dark mode for incoming emails [Solved with "Darko"]

So this new dark mode is really amazing, especially because it works in the compose window! But what about the message window (the email body).

Is there a way to get a dark mode there? Or do I need to create addon for that :smiley:.

So I decided to build addon that will invert page and shift hue.
And it looks better than I though (considering it took me only two hours to build and release it!)

Introducing, β€œDarko”!
