Add global tokens and the ability to display them in documents

See attached screenshot of Elizabeth West's post that includes some aggregated statistics in the first chapter to produce a summary card. Brilliant stuff but it would be cool if instead of hardcoding those numbers she could have entered a global token instead. Something like the following: Word Count Total {{!sw_project_word_count}} Which would then automatically show the total word count for the project. Things like tab word counts for the chapter, total word counts, (total AI words generated for that chapter and project etc...) would all be cool things to be able to drop into a document.
