Thank you for the excellent extension!

Could you add an option to show the extra vertical space (for short pages) as black instead of white? This would make it clearer where the page ends, as well as avoid a large wall of glaring white area.

Thanks!

Yep, that's a good idea, easy to implement.

Perhaps allow the user to specify the color via a hex string.

Yeah, I'll implement a simple setting allowing you to specify a css color string.

#22 implements this. Can you by any chance test it on your local machine and tell me if it works as expected for you? It it does I'll look at doing a release with it early next week.
