When creating a new page style Open Office appears to create  the new style 
from some internal presets.  It would be more useful if it created it by 
copying the existing selected style as that is most likely that a variation of 
the existing selected style is required, for example between Foreword type 
pages and main body pages.  Alternatively introduce a 'copy & modify' entry on 
the styles selector as this would probably be even more obvious and easier to 
document.

Using styles is a key feature in Open Office, and is one I find is much 
misunderstood.  Anything which makes them simpler must be an advantage.
