What is [[logseq]]'s [[document mode]]? I sort of want it to be a mode in which I can write free form [[markdown]] and have it let it be, without adding bullet points like in [[outliner mode]].

Let's see if it's that :)

This is a Markdown heading.

This is another Markdown heading.

This is a paragraph within that second heading.

Hmm, judging from the error message this is more likely to be all somehow embedded in a single block (?).
