it is a good dark mode plugin but needs improvements. Why does it change the colors of images and Google ads? Also, add a toggle. If you can improve that then I think it would be a perfect dark mode plugin. Thanks.

would be great that there also will be an option to use this plugin as a toggle, not only as a widget. and some manual or help documentation could be great. just found some info on the site. but wasn't able to solve my case.

With this plug it is much easier to read text on a monitor or display. A toggle as a pre setting for al pages, would be even better.

Incredible! I've been waiting for this for so long, I can't believe this finally exists so that my blinding white website can have a dark mode for sensitive eyes, including mine. I got some photos that look like they're negatives (inverted colors) but i think i can fix that by removing my background picture. Thank you! Thank you! Thank you!

The way this dark mode works (the JS library it uses) is one of the best I've seen. I hope customization gets better. The size adjustment sliders in the backend aren't the greatest.
