Conditional logic to send an email

Would be good to add a conditional logic command to allow to send to an email address that is entered as part of filling in the form.

That is possible. Please check this guide: http://www.jotform.com/help/167-How-to-send-to-a-specific-email-address-based-on-a-selection. But if you simply want to send an email to the submitter, you can just create an autoresponder email:
