How big is a single idea in a literature note?
I was reading the following two passages written by Martin and Mitch when I realize a seemingly simple yet complex question, how do we define a single idea/core idea in a literature note?
Let's say I just read a passage on how to make a cake and create a number of highlights and comments. Now is the title "how to make a cake" a core idea? Or should I go into more detailed title like which flour should I buy or how do I use the oven? If I need to go to the detailed titles, does it mean I need to create a separate note for each title?
