Don't want a field to take up visual space when empty? Set the field to hide when it's empty from the command line.

Fields are prompts, not chores. While you may want to consider the prompt each time it comes with a supertag, it may not be relevant every time.

Use the command line (cmd/ctrl+k) to "Set Hide Field Conditions" to hide when empty. It will be easy to add to the node whenever you need it.

You can do the same thing through a field's configuration.
