I teach undergrads, and every year basic computer skills get worse and worse. I guess it’s not entirely their fault, but things like just asking them to save a file to their computer is insanely difficult. Lots of universities are starting to get task forces to figure out how to teach (or where to teach rather) basic digital skills, it it’s all going to hit the workforce really soon en masse.

In high school I had to teach a kid how a mouse worked.

I mean, I know millennials who don't own a computer. Just phones. They got young kids. Not sure if those are alpha at this point or whatever, but how are they supposed to learn it if they got nowhere to practice?

Quite a few working class kids and teens grow up like this.

You can absolutely configure Windows to open folders -- and all other shortcuts -- with a single click, and IIRC one of the knocks against Windows ME was that this was the default option. And it was godawful, along with the "click" noise it made on navigation. (I think it was WinME. I've probably suppressed the memory, and rightly so.)

But the long and short of it is if you want consistency between your UI's in that regard you can indeed have it.

I use KDE Neon and have used Kubuntu before. Double click to open a folder is the default, same as Windows.

You get one guess.
