FB Plus is vast!

I have had FB+ for over a year, and I am still figuring out it's many options and advantages. I just figured out accidentally today that when you are repeating a challenge, if you click on a workout video on Dashboard it tells you what option you did the last time (if you are doing one, like FB Complete, that has different options.) Duh! I have been making calendar notes, and I realize now it isn't needed! Pretty great feature.
