A good plugin to make your site dark. But there are a few things that will be improved in the future, I hope so.
Not quite correct work with png format. Text written in black is almost unreadable, text in red is visible well.
Sometimes the plugin itself glitches, stops switching to dark mode. I did not understand why this happens, but in Google Chrome, it stopped working, and in Edge works fine.
Several times it did not work on mobile.
A little more work on the UI\UX and add themes...

In general, I am satisfied with the plugin. Since they are at the beginning of the road, you can expect rapid improvement and development of the plugin.

Thanks Darkmysite and Appsumo :)
