Runtime configuration data that may be user specific or zettel specific
Some metadata of the runtime configuration may be overwritten in an user zettel. A subset of those may be overwritten in zettel that is currently used. This allows to specify user specific or zettel specific behavior.
The following metadata keys are supported to provide a more specific behavior:
| Key | User | Zettel | Remarks |
| footer-zettel | Y | N | |
| home-zettel | Y | N | |
| lang | Y | Y | Making it user-specific could make zettel for other user less useful |
| show-back-links | Y | Y | |
| show-folge-links | Y | Y | |
| show-subordinate-links | Y | Y | |
| show-successor-links | Y | Y |
