I love that feeds (eg. Stripe & MailChimp) log their outcomes in the notes section of the respective entry records. For example, if Entry 1234 triggered a Stripe feed, a note will automatically be added to the entry stating “Payment has been completed.” If a MailChimp feed is triggered but fails for some reason, that is also noted. This is useful for various reasons including confirming that conditional logic is working as expected…Or noticing that a birthdate field needs to be reformatted before sending to MailChimp (https://docs.gravityforms.com/gform_mailchimp_field_value/#1-format-birthday)
I know one can dig through “Settings” -> “Logging”, but I think it would be very useful to also log which notifications have been sent for that entry directly in the entry view. The send date & time should also be noted since it is possible to resend notifications after the submission date.
