I am referring to the much-longed arrow key navigation in normal mode (not in presentation mode). Why to go for pgup/pgdown for it.
And, the design and orientation change issue, I am referring to, is not only limited to pptx but in office 2003 formats too.... What kind of document specification you want?
i have been involved in making more and more ppl in my college to use OO than going for pirated MS Office (or asking themm to shift to Linux because OO exists), So, these are some of the weak points of OO I have found myself. Once college gets open, I can give you a much bigger list based on large user experience. But I am not much worrying about it as OO ppl are doing an impressive job of improving the software but not implementing a simple feature which saves lots of time is a strange thing (read above).
