I played around with the file transclusion for markdown files today and I might have hit a minor bug.
For testing I created two markdown files from using the built-in template for Cornell notes.
Then I created a third markdown file which just had two lines with file transclusions. It does show me a combination of both but the first header for each transcluded file was missing.
I then created some simpler files on may own and for those everything worked fine - including the first header. Finally noticed that the files generated from the template include colons. So I assume transclusion wants to skip any metadata entries at the top of the transcluded files. However this is not metadata but a valid header.
Can this be fixed or would it violate MultiMarkdown compatibility ? If it can’t be fixed maybe worthwhile to change the templates and add a note about this in the help section to not use colons in the first header of a transcluded file.
