It would be useful to be able to create more detailed table of contents with sub-tables of contents for each chapter, like in some PDF files. This would allow better organization and structure of the notes. Moreover, it would be convenient to be able to specify the exact location where a chapter begins, so that the link from the table of contents leads directly to the right position on the page, and not to the beginning of the page.

Here is a visual example of what a more detailed table of contents with sub-tables of contents could look like:
