Calendar Alerts is a helpful reminder of important events coming up for people on your tree. But, as well as "Send a greeting", I would like to see a box to click on which we often see elsewhere, "View in Tree".
My reaction to one of these Calendar Alerts is (only too often) "Who?". I am sure most of us don't remember who the person is or where they are in the family tree, except in the case of the closest of relations.
