The problem with serving over WhatsApp isn't answering: it's that a week later nobody knows what's left pending, and the only way to find out is to open chat after chat.
Here every case that needs someone comes out as a card on the board, in its stage's column, at that moment. A new account already comes with nine labels and the board set up: you don't start with an empty screen.
