I have updated Sims Challenge tracker with a new Trivia report that appears for each Save file. It shows a number of useful charts and graphs with a summary of what's going on in your save file. You can use this to discover tendencies you never knew you had!
I have also improved the list of traits on individual sims, adding a new Trait Category called "Aging Up Traits", and organizing the traits list on individual sims' pages so that traits are shown in a more logical way on a sim given the traits' age groups.
