Rated 5 out of 5 stars

An excellent and practical dark theme!

There's just one thing I don't care for—and it's just a quirk, not really a problem: It hides the scrollbar slider until you hover right over it. This means you must actually take a moment to "hunt" for the slider before you can see it.

I like the idea of hiding the slider when not scrolling—but I think it'd be better to show it again when the user points anywhere on the scrollbar.
