Just want to let everyone know that YAML frontmatter is typically removed from the source code when rendering, and the variables stored are used as metadata for whichever app is reading it.
Right now we aren’t using it to store anything, but in the future, plugins would be able to access a built-in way of making decisions based on the data inside the frontmatter.
This may mean showing some UI that contains data, such as tags showing as a tag list on top of the file, or links that render as “related” somewhere else. That would be entirely customizable by the plugin and out of our control.
In the meantime, since this metadata is almost always hidden from view in other apps, we’ll be doing the same.
I do recognize the use case for some kind of user-defined front matter that’s different from what “markdown frontmatter” usually means. You can (and should) just use plain Markdown properly and do it like this:
tags: #mytag
links: [[My other file]]
