For the time being, the feature you are talking about with Countdown timer is not available. But as we promised to listen our customer’s valuable needs, so we are taking a note on it and it will be added for sure in the next update that is scheduled this week.
So I would recommend you to purchase the plugin before the offer price goes end. And I am assuring you that the feature you are asking will be in next version.
Let us know any more thoughts on your mind, Thank you again and Regards.
