Keypoints should integrate with MultiMarkdown and/or Pandoc to display a formatted preview of its notes and to directly output to common formats.
MultiMarkdown/Pandoc integration would also allow formatting of in-text citations and to generate a bibliography of formatted references.
In case of Pandoc, additionally integrating with Pandoc Scholar would also allow to include metadata with the generated document and to support semantic citations (like "cites as evidence", "uses data from", "refutes" etc).
