;;; Fake org-roam -- oni-org-exocortex
;; I tried using org-roam v2 with Orgro, but it didn’t work. I’ve only been
;; using org-roam to more easily find and insert strings. The file renaming in
;; v1 always seemed to have some issue, so I never really used that. And I
;; didn’t even look any further into any of the functionality. So these
;; functions are my re-implementation of the convenience of org-roam. This way
;; Orgro still works and I can easily build up my knowledge base as well. I call
;; it fake org-roam for now because I’m too tired to think of anything else,
;; it’s not actually enough to be a fake anything.
