I would love to see a rules engine built so multiple actions could be taken at the same time.
For example, a rules engine would go something like this for the form button:
When a user converts on this page, do the following:
Webhook #1
Webhook #2
Infusionsoft
Salesforce
Send email to respondent (fulfillment/transactional email)
Execute form post
Go to URL
All this would happen when a form is submitted in this example.
