Idea: View that displays ancestors with no father/mother

I primarily use FamilySearch not necessarily to go looking at names for whom I've already done research, but to make my family line go back as far as possible. As such, what I'd like to see is a way to jump to the ends of all my family lines. For example, a lot of the family history work on my Dad's side has been done. What I'd like to see is where there's room, so to speak, for me to add more names to his line.
