tiny addon, big selling point. simple function, easy to use, just like a single pole, single throw light switch for a room (not one of these 'smart' ones connected the internet). it operates like a light switch should, instantly and simply. it stays on until you turn it off, and vice versa. it would be great to have a blacklist/whitelist option for specific sites (unless i missed it, as i did not read the docs in their entirety yet), although the included list covers a lot of major ones people visit. all in all, way better than 'dark reader' addon if you are just looking for a simple catch-all solution without all the added overhead that dark reader packages with its features. thanks Bernard!
