The real issue is that some people have a fundamental lack of understanding of what Word is and what its design parameters require. It is a word-processor that provides for text and tables to flow in columns, across page boundaries, etc., not a: page layout
program like Publisher; presentation program like PowerPoint; spreadsheet program like Excel; or database like Access. Yet all too often people complain that they can't use Word the same way as those other programs, that: they can't drag pages around willy-nilly
regardless of what happens with content that spans a page break; it doesn't have tabs and calculation functions like Excel; and so on. So, just as you can find a few threads with people agitating for Word to provide tools for moving things around at the page
level, so too you'll find threads with people whingeing that Word doesn't provide Excel-like tabs, etc. The mere fact such things can be found proves nothing more than a lack of understanding on what a word-processor is. If you want a word-processor, use Word.
If you want the functionality of a different program, use that.
As has already been discussed in this thread, Word does have tools for moving content around but, in accordance with it's design paradigm as a word-processor, that's at a content level, not at the page level.
I'm not dismissing anyone's request, but what people complaining about the lack of ill-conceived functionality do need is a reality check. If you want you can ask MS to provide whatever features you want, via
http://word.uservoice.com/. Alternatively, you're free to use any other word-processor you might prefer. Just don't expect to find one with the same functionality as Word, let alone the
ability to drag pages around willy-nilly the way you expect Word to.
