On accordions, I'm of the opposite opinion... sort of.

I love outliners such as Workflowy and Dynalist. I'd like most textual content to look more like them. It's really great being able to expand/collapse/zoom into entire sections, link from one section to another, etc. You can expand everything with a single command and you should also be able to flatten the tree and read it like a normal page if that's how you like it.

Regular pages with accordions are just a poorer version of this. I'd like it to go all the way in that direction.
