i actually use this at other browsers its very cool!

Stylus should rotate dark styles with normal styles based on geoposition and timezone by default. Similar to the https://addons.mozilla.org/en-US/firefox/addon/automatic-dark https://github.com/skhzhang/time-based-themes

I use this to write CSS to fix broken sites and remove overintrusive ads that escape ad blocker. Actually works, unlike new Stylish. Interface a bit clunky, hence 4 stars.
