List of links /to/ document + character linking shortcut with fuzzy search helper

I’d like to use links to hyperlink all references to a character. Similarly, I’d like to click a character and see all places they’re used (that I’ve linked at least). I realize this is a lot of work on my part to set up all the links, that part is fine- but I’m curious if there’s already a way to view the list of links to a document? If not, that’s a feature suggestion.

The other part of this is- when I select a chunk of text, if there was a shortcut menu under Link to a document that was Link a Character which then pre-populated with characters that either match or are likely to match, it’d be a breeze to set those up a lot faster. That’s the other feature suggestion.
