Show Next Button, when enabled, allows you to put the next button at the end of every question that allows respondents to click it and move to the next question after they have answered the current question. This button can be used when you have disabled automatic transition and would want your respondents to manually navigate to the next question.
This is how it would appear to the respondents if the Show Next Button is enabled.
