I have seen users add A&W ("Alive and Well") in the clinical comments section frequently. This is a common way to note that you have inquired about a family member's health and there were no concerns.
I think that adding these features would entice users to use the pedigree builder as it closely mimics the way pedigrees are currently drawn by hand.
If "Alive & Well" option is selected, "A&W" should be displayed under the pedigree node on the last line (e.g. under the name if it's present).
If "Deceased" option is selected, another menu option should appear with "At age" and "Cause" fields. If these are edited, the information should be displayed under the pedigree node.
