Extremely flexible; if a site doesn't play well with a certain format, there's like three more to fall back on. On top of that you can extensively change how the "dark" theme is displayed! Features support for blacklists and even time scheduling. This is the best dark-theme extension I've ever used.

Basically a requirement for OLED devices. Very easy to turn on/off per site basis

太好用了，很智能，该深色的地方变深色，不该的地方不变

Just reduce the contrast and this extension will make your day to day surfing and reading much easier.

Perfect
