From my experience, apps are not developed anymore with power user in mind.

There use to be a terminal app (DOS) at a company I worked at which only worked with shortcuts, the learning curve was pretty steep but after a while using it you could be pretty efficient.

Now they replaced it with a nice UI but you don't have shortcuts. Maybe there wasn't enough demand for it.

In programming we mostly use tools we also use at home or elsewhere, so the learning cost is worth it (if I learn VIM, I will be more efficient at every programming job in the future, not just this one)
