I've lost count how many meetings I been in where I completely lost what the speaker was saying because someone was clickly clacking on their keyboard the whole time. The requisite "Whomever is typing please mute yourself!", never works because the typist is never paying attention.

There should be an app that logs you into your mandatory conference calls so you can get the checkmark for attending, but completely isolates the user. Then, when you suddenly have to talk, and someone pings you, it will call you, and while its ringing it will play a pre-recorded, 'Oh damn, I think I'm having connection issues, can you repeat the question?'
