As per the following ressources, page-margins is a pretty complex and important craft. One of the reasons e.g. LateX looks so nice is it's parge-margins defaults. Fortunately there exists good 'fallback' defaults (described in the ressources below). Since I always use time on creating page margins for my templates - it would be a strong feature if I could simply choose between a few predefined sensible defaults. This would also make most libreoffice documents so much nicer than MS word.

There do not exist margins which are good per se, but it depends on the purpose of the document and the environment in which it is used. For example, compare writing a single sheet business letter in USA on legal paper format with a technical magazine on DIN A4, or a Japanese chapbook. Therefore LO has the concept of document templates, so that everyone can make a set of his favorite document style settings. Of cause you are right, that not everyone will know about typography. For those some well styled templates are useful. Perhaps you can generate some? You can use our page http://templates.libreoffice.org/ to provide them. And if they are generally approved, we can discuss to deliver those together with the program. I will set this issue to new, so that others might read this task and help in generating improved templates.
