Ability to See All Skills Mastered

It would be nice to see all the skills and their levels of mastery that you've acquired through out all the lessons. I do have the ability to calculate the amount of skills I have, but I don't see the specific skills I have. In order to do this, I would have to go into each lesson and hover over each skill I have attempted to see exactly what the skill was. A compiled and/or summarized list would be nice as it's a great way to set goals and milestones for one's study.

I believe there was a feature similar to this years ago, but upon trying that method (Accessing 'World of Math') I cannot get it to work on my end.
