How to Keep Track of Post-It

Sogalon is 177 years old, which is a lot of life to cover. And it's a multi-faceted engrossing plot. How did you keep track of it all? Thank God for Post-It. I think my wall is so covered in Post-It so that I can't remember what the original paint is. So I knew when I was taking it on that even if she spent a hundred years doing nothing, that it would be something pretty epic and pretty too... It was too much to sell to contain in my head.
