Suggestion: Allow staff to set a topic timer, which counts down to a chosen date/time - BUT, doesn’t close the topic once the countdown is completed.
Reason: Sometimes I want to set a date for submissions, but don’t want to end the discussion once that time has passed. Once the timer is completed, it could say something like "Topic timer completed on dd mm yyyy at hh:mm a/pm. Once the timer is removed from the topic, that message could disappear.
