There is a bug in the Sphinx layout, where the subchapters of a chapter are invisible even after the chapter is clicked. It is a pain when you are trying to figure out the different sections in a widely variable chapter like the performance chapter, to know which section to read without having to click one-by-one to find the right part. I am not sure about what it would take to show the subchapters in the outline view to make this easier for someone to figure out. Or maybe a TOC for a chapter at the beginning of the chapter? This would really help a lot. Sincerely, Matthew.
