When I use Scrivener I tend to have quite a deep hierarchy of documents. Often, I'll use a child document for notes that I will write up in its parent document.
Currently, when I view by project in Group Mode, the word count of every sub-document is included in the "Total Words" column for a given document. How can I change this so that certain sub-documents (e.g., the "notes" documents described above) are excluded from the "Total Words" column?
