Doesn't work well if the site already has the dark mode on the site it inverts it to a light gray almost white. Also hides some elements on sites. If you turn it off it forgets all your changes.

I like it for it's ease of use, but is there a way to remember a site's preference without constantly toggling back and forth? If you open a link in a new tab, as an example, you likely have to change the settings in the new tab - when you go back to the original site, like a Reddit, you have to change the setting back again. Is there a way to remember the Reddit preference?
