Software / Addons / Plugins / Websites with a mostly bright background, are for me the most questionable phenomenon, probably without a conspiratorial .. haha ​​.. background.

Why are almost all monitors / TV's black?
They stand for the empty space to the requirement of material value.
That can be planets, Video content or virtual buttons such as icons and menus.

We need light to exist: there are suns for that.
And a sun that lets us recognize everything important in a pleasant way, is the creation with the name "Dark Reader"

Thanks for your Light
