 This works well enough if we just want to build something, but there's a problem: we haven't indicated to Nix that we want this output to stick around, so it will be deleted the next time we garbage collect. To fix this, we can write a wrapper function that also makes the output path a garbage collection root.

 Let's also rebind some keys. Preserving evil's =[= and =]= bindings doesn't make sense to me, and =C-r= makes more sense as a redo binding than =D D=.

 The unlinked references section is turned off by default for performance reasons, but I've never had any serious issues with it. Let's turn that on, and also make sure backlinks are unique.
