Sounds good generally! Thanks.

Just a quick question:

> Plaintext (default): the old escaping behaviour and no doxygen command parsing. The only thing I would still change is the paragraph termination with 2 newlines instead of 1.

A single blank line between paragraphs sounds OK. If you mean adding another blank line in between, or a trailing blank line at the end, that might look extraneous. In any case, that sounds like a relatively minor implementation detail that we can discuss further as the PR goes.
