Ability to delete a submission using a button or a widget

I know you can delete submissions from the "submissions" page. However, is there any thought to adding this functionality as a button or widget?

I am not sure if I understand your query correctly. Do you want to delete the submission right from your form? Since the submissions can be displayed only to you when logged into your account, they can be deleted only from the submissions view. If you can provide us with more information on your requirement, we'll see what best we can do in this regard.

We will wait for your response. Thank you!
