I agree about the lookup sometimes being faster. It depends on your personal style of note-taking though. I found that when I had to draw a nice big diagram, it tended to be easier to find on a single-flip through. I also I tended to remember other things from that day as being associated with it, just because the diagram was in view while I was writing notes on unrelated things. It got to the point where I just put in a large doodle every few days if I hadn’t drawn anything in a while.
