Glad you like it. I can't because I don't have any idea about programming. Sorry. If so, I'd have changed a lot. Thus I needed to keep the original position of the elements and just changed the design
Unfortunately, the resolution of that wallpaper was only 1366x768. But if you want to search it, just google "Climb Mountain Climbing Rock Nature Cities" (I guess that's the name of the wallpaper).
Thanks for your advice! But I already tried it and what I didn't like was that I had to click twice to activate it. That's actually the only reason why I use and prefer Caffeine. Concerning the dark mode, I don't use it at all.
