Zooming with CTRL-Mouswheel is not intuitive:
If you zoom in or out with CTRL-Mousewheel one usualy expects that the position 
under the mouse cursor doesn't move. This is allmost a standard behaviour in 
most image editing tools but also in MS Word.
OOWriter zooms allways keeping the page left aligned. So if I want to enlarge 
the right part of the page, I have to do two steps: Zoom & scroll to the right. 

Even worse it behaves when you zoom out and allow multiple pages to be viewed 
side by side. This is even a bug and is very anoying, if you have a high 
resolution monitor where multiple pages are very useful. If you zoom out from 
one page to a two page view it's unpredictable where on which pages you end up. 
It's not on the page where the cursor was and also not on the page over which 
the mouse pointer was.

Thanks you for taking care.
