Adding Skill Total to Profile

I'd like to suggest that there be a total skill count added to the profile just as there is for videos watched. While you can see how many skills there are to master in a unit, many units have overlap. This makes it difficult to see how many skills you've mastered particularly if you are interested in competing with others in class or in earning Sun badges. This seems a simple thing to add as The World of Math used to be able to quickly calculate this total. Thanks!
