The problem is that I often do work team quizzes where people get distracted by emails, phone calls etc meaning they don't respond for a number of questions. In this scenario the minimum 15 second timer plays out for every question and as I am often under strict time limits it unnecessarily lengthens the quiz presentation time. Would your developers consider a 10 second option as traditionally I have always successfully used that? 15 seconds is too long for punchy quiz responses.
