Note that @ShaneNZ has recently discussed this idea in detail, including the idea of creating a plugin to address it.
To address ShaneNZ’s points:
If the user has a vault where a large number of commonly used nouns correspond to existing note titles, then the outgoing unlinked mentions feature might not be very useful, but I don’t think that, at least initially, it would be necessary to tweak the feature for that use case. The default would be for the feature to be off, and it would be up to the user to see if the feature is useful for a given vault.
Fair point. I’m not a developer, but it seems to me that, if the current “unlinked mentions” implementation can search through the content of all other notes, then it should be possible to search through the titles of all other notes for matches to the current note’s text. But I guess it would depend on how long the current note is.
True, but doesn’t that point apply to the existing “unlinked mentions” implementation as well? It seems like a more general problem, rather than something specific to the idea of outgoing unlinked mentions.
Interesting point. Again, this seems like a problem that is general to the idea of unlinked mentions. Perhaps the new aliases implementation provides a partial solution. At any rate, for my purposes, at least to begin with, I would only want to search for actual titles (and aliases). In other words, I simply want the current “unlinked mentions” feature in reverse.
Anyway, thanks for your deep thinking on this!
