PURPOSE ======= For now, the host can't go back to the previous screen on a live session. Why would he want to go back? Misclick, want to display again the result, other SPECIFICATION ============= On a live session, let the host go back to the previous screen. Do not "restart" the questions but display the graph with the results. This back capability is independant of the "back button" survey option. Even if the back button is disabled on the survey configuration, the host must still be able to go back during a session.
