Nav Link Header was beyond my coding abilities to understand, but I looked at other plugins that added a header or footer and stumbled on “Rich Foot”, which puts inlinks and outlinks in a footer in the markdown editor, and used simple Javascript. I hacked away at it a bit and was able to make it do what I wanted. Now I can remove those ugly dataviewjs blocks from my journals, but still see related files for each journal on the screen. Thanks @holroy for nudjing my head in a slightly different direction than it was heading so I could find a great solution!
