Currently when you click on the "Read the documentation online" link on the org homepage, it takes you to a monolithic file which seems to be either exactly the same or very similar to what you get when you click the "single monolithic file" link. I don't know if this was intentional -- until recently it was a hyperlinked different-page manual, and I just want to report that it changed in case it was by accident. I don't much have a preference but it's easier to bookmark where you are in a hyperlinked version.
