The header and footer in a document are great for providing coninuity and organisation throughout document pages. More evident once the document has been printed. An easy oversight by many but very useful and worthwhile implementing.
MS Word is useful for authors requiring printing features not found in the software they use as well as MS Word users. Personally I use ‘Nimble Writer’ for my projects and export to PDF for digital formatting. Physical printing requires an export to .docx file to open in MS Word to print a book.
