Alright, I can agree to that.

A similar example is country drop-downs in web forms: United States if often first, because most visitors come from there.

This is deliberate. You hardly ever need to change port number.

In 4.1.8, the tab order of the fields in the Login dialog is Host name, Username, Password, Port.

It should be Host name, Port, User name, Password.
