I use a terminal because it is NOT a GUI, significantly improving productivity once learned. I cannot grok this, it feels like a step in precisely the other direction.
For instance, code signing and notarizing a Mac app is a huge pain. It's not the kind of thing I do all the time, but it took quite a while to figure it out. I spent a few hours piecing together StackOverflow answers, assorted blog posts, and the threads on Apple's Developer Forum before I got it to work. It would be great if this workflow could be encapsulated an app.
