How about adding a distinguishing icon (or color) to the backlinks (both linked mentions and unlinked mentions) that are linked from the current page to the backlink?
@WhiteNoise An alternative would be a feature that allows to filter out two-way arrows in the local graph of a note. But I prefer a filter or separate category in the backlinks pane of a note.
Either way, I can’t imagine such a feature can be missed when serious about processing thoughts and notes.
