I agree being able to tab or subdivide a notebook would be helpful. I have found work arounds where you created tabs and links but this seems to involved to do as I'm taking notes. I'd like to create a tab that starts a new subsection in a notebook. For example. I have a notebook that contains biograpihies and data on people. The information belongs in a single notebook but I don't want to scroll through every page to find and update a single biography. Each tab should be a stand alone section that can be updated independently but still be part of the greater notebook.
