Open Office needs to come preloaded with the better dictionary and thesauras plus and easy graphical interface for adding the extensions that are available from Sun's site. This interface needs to be idiot proof or the Windows users will not move.
Developer comments
OpenOffice.org uses standard hunspell/myspell dictionaries which are
available for most languages and are installed automatically via the
language-support-writing-* packages. If a dictionary happens to be
missing for a particular language please file a bug report and include a
link to where the dictionary can be obtained if possible.
Also, a bug report has been filed against shared-mime-info[0] to
identify OpenOffice.org extensions in a way that can be associated with
the Extension Manager for installation. So this should be corrected in
time for Ubuntu 8.10.
