When viewing multi-page documents, Microsoft Word allows you to click on the 
grey space between the pages to switch into a mode where all the top/bottom 
borders of the pages, the page number row, and the grey area between pages are 
not displayed anymore. This saves an enormous amount of space when working with 
documents, especially on resolutions like 1024*768. 

Unfortunately, OpenOffice does not offer such an option. The difference is 
huge, as demonstrated in attached screenshots: OO wastes a third of the screen 
space. Also, it is VERY annoying to work like this with multi-page documents 
whenever you approach page breaks.

Web Layout does not offer an alternative to this. This is needed when you work 
with a document that will eventually be printed (thus you need to work in print 
layout, not web layout), but is also viewed and worked with on the screen a lot.

Examples, for when this is needed:
- Writing a 100 page thesis: In the end the document will be printed, and while 
working on it you also need to take care of the layout. However, during all the 
months you work on it, you don't need to waste a third of your viewing space by 
seeing the page borders. They never change. It's extremely annoying, because 
you have to scroll up and down all the time, just to see what you wrote in the 
previous paragraph (because the space where you would see it is all occupied by 
page borders). Many of my fellow students switched back to MS Word because of 
this.

- Working on a long business document, that gets updated every week or so, and 
the current version of which is printed by management every couple of month. 
The situation is similar: The document only gets printed from time to time, but 
most of the time you work with it on the screen. Web Layout is no use here, 
because the document is for printing. 
In my company, I cannot recommend OO to laptop users because of this. Screen 
space is scarce and such a waste is not understandable. It makes people accept 
all the small disadvantages they hate about Word, just to not be confronted 
with this proplem on every page break.
