using filetags for marking nodes in org-roam as Zettelkasten main notes

My org-roam garden is a bit of everything, not only what you'd call Zettelkasten notes.

Perhaps not good practice - I don't know. But it is what it is. I usually refer to it as a commonplace book or a digital garden. It's never been only a Zettelkasten.

But lately, I'm trying to incorporate more Zettelkasten-y aspects into it. Namely, being explicit about creating 'main notes' (from the terminology of A System for Writing).

With that, it's useful at times to search only for main notes. filetags will let me do that.

In org, you can give a file tags with the filetag property.

e.g. #+filetags: :zkmain:

Then, you can set up the completing framework to include those filetags when doing an org-roam-node-find.

From the org-roam manual:

(setq org-roam-node-display-template
      (concat "${title:*} "
                    (propertize "${tags:10}" 'face 'org-tag)))

If I am consistent about this, it'll hopefully give me a way to emualte Zettelkasten 'folders' for main notes and reference notes.
