Is your feature request related to a problem?
This is not a problem, simply something useful.
Describe the solution you’d like
That the relations in a page that has been exported would have the possibility to be exported via YAML formatting, either in a separate file or at the top separated by two — lines. Ideally this would also work for import, but this request is mainly for Markdown export.
Ideally, you should even be able to decide which relations to export, or even be able to define how you would like the various relations are formatted in YAML (like, single tag, tags in brackets, sub-tags…), but the title, created, modified, and tags relations should always be present.
Give us a real world use case for this feature
Example of output:
Hi, thanks for posting a feature request! It looks like this feature request might be a duplicate of another feature request about YAML export, although that also includes import here. Do you want to merge the two?
