I'm glad to see people start to create these themes for Safari, although I do wish there were a way to preview them first. I purchased another one before buying Dark Theme, and even then, I was hesitant to take a chance.The one I purchased worked, but on several sights, the text was so dim as to be impossible to read. That's useless to me.Dark Theme is pretty much black background with white text (although it keeps color in icons, pictures, etc.). I've seen prettier, but it works, and it's a lot easier on my eyes. (For that matter, "prettier" often causes a number of problems. The more you try to do, the more some sites just get messed up.)Anyway, if you want a dark theme for Safari, I recommend this one.

I went to Wikipedia and the word “Wikipedia” couldn’t be seen when the Dark Mode feature is off. The words with a black/dark color cannot be read. Other than that, it is pretty good app.
