double headings for extra content
When the md file starts with # TITLE
and the toml file has [ '...md', 'OTHERTITLE ]
, the html ends up with
<h1>OTHERTITLE</h1>
<h2>TITLE</h2>
which is generally not what is expected.
I would suggest to only use OTHERTITLE for the link, and leave it up to the content file to provide its own title.
