I'm happy with Linux Mint 18, because it has included a dark theme that just works all the time. Fastest and easiest route to nocturnal perfection that I have ever experienced in any operating system. I liked it so much, I donated to the project. In my opinion, Mint-Y-Dark is reason enough to convert to Linux Mint 18. Meanwhile, I don't know what Windows and Ubuntu are doing, but they are not doing anything for me.
Mr. Developer, please. Think, for a moment, about the human body. In particular, have pity on the human eyeball. It is not designed to stare into the Sun all day long. Try to design your product so that it works in harmony with the user and is not harmful to the user.
