There are many people who are more comfortable with the display style of mind-maps; I wonder if it is possible to display a notebook (whose contents have been properly formatted as Chapters Sections, etc.) in the form of mind-maps? If there are no built-in approaches, is it possible to realize this functionality with the aid of some code?
Here is a start. Because in Wolfram Language "Everything Is an Expression" you can use built-in structures and parsers to view it as a tree. For example, this creates a notebook with some content:
nb = CreateNotebook["ComputationalEssay"]
And this transforms it into a tree
ExpressionTree[NotebookImport[nb, _, "FlattenCellGroups" -> False]]
You will have to make it more tailored to what you want but I think most of what you would need is well described in documentation.
