When one inserts a new section in LibreOffice it starts mid-page. This is the expected behaviour. However I do not know of a way to start a new page with a section. If one forces a page break the section starts one line down as the section is now after the empty line. This often means that I have sections that overflow a page by a line or two which looks messy.
How do I force a section to start at the VERY top of a page?
