Microsoft Flow Connector to allow for data collection
It would be very useful if you could allow Flow users to use data from individual bookings. For instance, I could check e-mail addresses against a list to confirm eligibility for the service (and send out e-mails in the case of a mismatch), assemble the data in an organised way by populating a SharePoint List, and automate e-mails with surveys days later.
That way users could create their own workflows for their particular situations without clogging up the Bookings interface for those who just want a straightforward way to collect appointments.
I worked around this by using "When a new event is created" Flow, but there should be 'native' way of doing this.

It would also provide a way to connect to Mailchimp via SharePoint. I think it is a needed feature for a small business that wants to keep in touch with its customers
