I realise this is a very broad and subjective topic, but I wanted to know if there are any good sources for best practices on organising the layout of a notebook. I often find my documents hard to navigate and confusing to read. So when and where to use the various styles of text cells, when input cells should be merged and when they should be divided, etc.
I have read most of the documentation on notebooks, styling, and formatting on the Mathematica website. So I'm aware of everything that is available, what I'm really after is recommendations of either online sources or books that discuss styling of Mathematica notebooks, maybe some exemplary notebooks.
