Improved & Fixed - Stopping now takes a deliberate five second hold and asks before it ends a session, so a stray tap cannot cut a recording short. - If that confirmation goes unanswered, recording carries on instead of stopping. - Monitoring no longer ends when you switch away for a moment. It picks the mode back up when you return.
