Read realtime what the user is typing in the other side

Current all chat solutions just show if the user is typing or not. Would be great to know what other side is typing. Never seen this feature in any chat solution.
This will boost productivity because we dont need to wait any more to the user finish typing the question to know what he wants, so we can just start looking for the solution asap, exactly like a real conversation happens ! we dont wait the other side finish talking to start thinking in our answer !
