When you are building a large tree it can be easy to lose track of how complete various parts of the tree are, and where it is weak.
It would be very useful to have a way to indicate and then report or display the degree of completion of various links and nodes in the tree. For example, a way to indicate how sure you are that a given individual is indeed the ancestor you think s/he is. Either a low/med/high or a percent certainty flag on the individual, which could appear in the individual's box in the Family tree. Also, for each individual it would be nice to be able to display key indicator status, particularly birth, marriage, and death. Perhaps small B, M and D icons that would appear in the box only if you indicate on their Person facts that you have solid documentation of these facts. Another useful attribute would be a general "degree of completeness" indication that you could set, so you can easily find individuals that need more work. Perhaps there is a current way to easily accomplish these goals that I've missed?
