I like that way too. We could have separate chapters for Radio, Recording etc. The only drawback is the fact that the manual chapter numbers will then vary between the targets, and as users tend to name only the section number instead of its name this might cause some misunderstandings. Not sure if that is too much a concern though.
How about putting an a "This target does not have the capabilities to <blaa>" so we always have a chapter for everything and the numbers stay constant...?
