Sounds like a feature for features sake. Your response also sounds like “but can you do this?!?!” Can’t say I’m remotely impressed. Anyone who needs this weird feature could just add a string delimiter to their markdown file, and use a Unix until to partioning. Still not sure why multi pages should be in the same file, sounds like a horrible “feature”. Each webpage has a distinct url with the last bit being the filename…

Also sounds like you have a conflict of interest to inflate the merits of this project
