Thank you for this. I would like to have read this, especially since I'm on vacation in Hokkaido now, but unfortunately your "clever" right-side table of contents overlaps the actual content on my iPad Pro running the current iOS. So, it's impossible to read the last 10-15% of each line, especially once the TOC expands to most of the height of the screen.

Please give a less "clever" and more traditional UI.

Thanks!
