The Writer Guide needs more input from people who understand the new features. I am often at a loss, and I suspect that new members of the team would be even more so, unless they happen to have expertise in some of the topics.
Many of the new features in Writer 7.5 (and some earlier versions) appear to be aimed at specialist users and/or MSWord compatibility. In many cases I do not understand these features and so I cannot write much about them. Blog posts by the developers sometimes give a clue but usually not enough context for me to understand the topic. When the Help for these features becomes available (usually one or more releases later), I can usually then figure them out and write something that I hope makes sense. But that is not timely for a guide that we’d like to be up to date and informative.
Because of this problem (my lack of expertise and the lack of suitable expert review and input), I have been unable to meet my own minimal standards for correct and useful content. Therefore, I am reluctant to continue to update this book.
