I'm more thinking about interviewers that seem to be continuously typing while I'm talking without following up on things I've said. Perhaps with a summary feature like this they could be more present, and make the interview feel more like a conversation than a verbal form.
Ah I see your point. I just pause when they start typing and let them finish. I consider it a polite indication that I let them finish storing what I said in longer-term memory and that at the same time I would prefer they focus on what I say.
