What are character name variables? (from v1.6.4)

A novel-drafting tool: on your book's page, click "Characters" and define, for example, john → Jonathan Smith. Then write {{f:john}} anywhere in your chapters:

- {{f:john}} or {{john}} → Jonathan Smith (full name)

- {{first:john}} → Jonathan

- {{last:john}} → Smith

Every export format and the audiobook narration resolve the markers automatically. Renaming a character later is a single edit in the Characters dialog — every mention

in the book follows.
