Margin Notes is something that I miss in many programs - word processors and dtp programs.
Like footnotes and endnotes, in a technical document margin notes is a very valuable feature. Workaround is to add text boxes to the margins (center column or left / right margins) - but it is always maintained manually. TeX / LaTeX have feature for margin notes and it is very usable in technical documents.
Is it possible to implement this feature in LibreOffice?
