Peter,
I had a very quick look through your update of Impress Guide Chapter 7
(Spreadsheets, Charts, Other Objects), attached the v3.4 template,
updated the formatting of the table of Mac info, and put the result
into the Feedback folder,
http://www.odfauthors.org/libreoffice/english/impress-guide/feedback-lo3.5/ig-ch7-spreadsheets-charts-objects/view
I think it's ready for copyediting or even publishing as it is, with
copyediting to be done when Hazel has time. Up to you.
