created as YAML has pro’s and con’s.
Pro: When importing a note created from elsewhere, one could easily maintain the original creation date.
Con: created could accidentally be changed or lost. This wouldn’t be a catastrophic error for the app, since the app could always default to the file’s creation date for created; but, it could be an issue for a user who wants to somehow protect created value.
Are there write-protected YAML, which could be altered only after a warning/alert? I imagine not.
