(I deleted what I wrote in that link. Here it is.) The leftmost editor is used to write the section (or chapter), & the rest are used to take notes for that section, or to keep old versions of that section as reference, or to work out different ways of writing a subsection, etc. (& this seems hubristic, but I think this app might actually be a watershed moment in UI & UX & software development history. There's nothing out there that lets you juggle contexts nearly as seamlessly. Microsoft Word & Obsidian have alot of lines of code & hours behind them, but in terms of how much they empower me to write & think, they're far inferior to this app. & if you look at the html, you'll see it's only 750 lines of code, of which only 670 lines are actually used. So it's also extremely maintainable & forkable.)
