What this extension is doing is freaking amazing, think about all the different ways of styling websites that web developpers use and this extension gets them all into an easy on the eye at night colour scheme. Gotta say that this worked much better than I had anticipated (even on mobile phones!), but that doesn't mean it's perfect. Only issue I have is when swapping between sites while browsing the screen goes white for a very short time and back to black. You don't notice this on a white colour scheme, but it is quite overwhelming at night with this extension turned on. It's not too big of a deal and I doubt that can be fixed, but if it could that would make this extension impacable.
