I don't have an issue with people using CLI. But it could be better.
So Midnight Commander is at the best it could be? If everyone thought like this then there'd be no innovation.

Look at this example, using CTRL + SHIFT + P for taking screen shots (I know it isn't CLI). If this was reduced to one button, wouldn't that be a more intuitive solution?

Simplicity doesn't mean less capable. It's all about working smart.
