Person typeahead lacks details
Whenever a Person field such as Assignment provides type-ahead list of matching persons, the information is very limited. Most of the time, it only shows their name. The problem is when there are multiple people with the same name, you cannot know which name is which person. The person information is available, but since it does not have enough detail to distinguish who it actually is in the typeahead popover, it can become very difficult to select the right person.
It would be very helpful to include showing the person's email address with their name so that at minimum, we can distinguish two or more same-named persons by their email id. This would apply anywhere a person typeahead exists such as task assignment, sharing, etc.
