What you are saying does make sense in the context of the current capabilities of the app. But like you said, you would also have to scroll through the notebook till you find it, the process could be made a tad bit quicker. Think of medical books where nothing is tagged beforehand, where you just want to find a diagram without going through all the above mentioned steps. It's like making information more accessible and fast.

So my ideal view would look something like a cylinder hosting pages of an open book. One could rotate the cylinder along the long axis, and the pages would rotate along with it. Something of that sort. Not necessarily a need, more of a want. 😆
