Is there a good way to display word count while using Goyo?

I love goyo, but would also like to see the word count. Is there a recommended way to do this?

Review the five-comment thread and the current Goyo behavior first; the issue does not name a file, test, or entry point. Determine whether the recommended word-count setup belongs in documentation or requires a feature, and consider the work complete only when users have a clear, verified way to display the count while using Goyo.
