Notice after submitting answer

Hi Rahul!
Thank you for this amazing plugin. Everything works nice. However I’ve noticed that after sending an answer no notice is shown, and fields remain filled with text. So, there’s no way to realize whether the answer has been sent. As consequence I receive the same answer many times, since the person clicks on the submitting button several times because there seems not to be any action taken by the plugin.
Any suggestion?
BTW (i know nothing of coding)
