I have some seasonal surveys that I keep up year around for residents to view. Since I leave these up I would like to turn submissions off, but still allow people to view the results. There are some work-arounds like hiding the form or altering the form. I think it would be beneficial to have a button in the settings to turn on a lock, pause, stop and or etc, the Survey. Then when it's time to take surveys, I can turn on/open the survey for more submissions within said period of time.
Another option that could be neat is a scheduled survey, open up the form for x amount of time then the survey closes but you can still view the results for however long.
