James:
I do something similar, simply writing post-it notes in the curriculum binder to jog my memory next time the class is taught. When the binder gets updated, I evaluate whether to permanently add this or not. Sometimes there's topical information that's relevant for a time, but loses it's significance, so I'll toss it.
You're right about classes being dynamic - each one just a bit different. We need to be flexible in our delivery and choice of content.
