I think this would be a very simple addition to the Family Page. When looking at the family tree and you click on an individual's name only some of the information on that person comes up (in the box to the left), but when looking at the Genealogy page of an individual much more information comes up (such as notes).
I think that it would be great if you could go directly to a person's genealogy page from the family tree. When you are on a person's genealogy page there is a link that says "show in tree" to the right. Why not have one the other way around as well? When clicking on a person's name in the family tree the box in the left could have a "show genealogy page" link.
