- 2.8 Drawers
- 3.2 Column width and alignment
- 3.3 The Spreadsheet (4 rather technical pages)
- 7.4 Property Inheritance and 7.5 Column View
(do beginners really need properties at all ??)
I would agree on this list (except maybe drawers).
If there is room for additional sections maybe:
- include the org ref card as an appendix (which in itself offers a
very good overview of org)
- include some pointers into getting emacs for different OSes and
getting started with emacs. If there would be an O´Reilly book on
Org-mode this would be in the first chapter or so. For people who
started using emacs because of org (like me) the current Introduction
might still be too cryptic (?)
