Automatic Successful Delivery Confirmation
After sending an email with protonmail, you will see a message that the email was sent, but that doesn't mean it was actually delivered or received, (which by the way is not the same as opened - that information is private to the recipient).
I have sent emails with protonmail that arrived much later than they were sent, even weeks! Appointments have gone amiss because of this. Also, there is always a chance that an email will never arrive at the destination.
It would be good to have a visible SIGN or checkmark in the sent email list that CONFIRMS time and date of delivery. Again, this is not the same as knowing if it was opened by the recipient which is private.
A similar feature exists in Yandex.com. On the page to compose an email there is a button that says 'notify me'. If this option was selected and the mail has arrived, you will get a "Successful Delivery Report" in the form of an email. This has proven to be very useful when a server of the reciptient was down, for instance.
A 'notify me' button is not ideal. A permanent or default setting would be better, because there are always times you forget to select the button. To receive the confirmation as a separate email is also not the ideal because it will easily overcrowd the list of emails and results in some unnecessary cleaning work.

Agreed, the SMTP Delivery Status Notification would be awesome. Roundcube implements it as well

Delivery confirmation is an SMTP feature (Delivery Status Notification). Other email clients besides Yandex.com also implement it. I agree that would be a useful feature.
