I would like to propose the ‘inline PDF’ feature.
When using Evernote, I often ‘scan’ documents into PDF to archive them digitally. When using their GUI based applications, it would show my scanned document inline.
- There is only one attachment
- The markdown is empty except the link to this attachment
- The attachment is of type application/pdf (or .pdf)
- In rendered view, show the PDF instead of the rendered markdown.
