I'd found it very usefull, to have the option - for example as a new point in
the section-context-menu of the navigator:
'save section as a new document'.
This option should also be available for the sections in a globaldocument, that
contain the linked docs.
Background of the whish:
Having that pissibility I could set the sections of the globaldocument on
'writable', do all changements directly in the globaldocument and than overwrite
the linked docs with the sections of the globaldocument.
I used to work in a simular way with Lotus WordPro. A globaldocument in Lotus
was called masterdocument and when I saved the masterdocument, WordPro proposed
to save also the linked documents, what I could accept or refuse. By accepting
all changes that had been done in the masterdocument where written to the
source-documents.
When you have for example a catalog or a manual that has to be updated every now
and then, usually you have to change various documents. It is much more
confortable, if you can do that directly in one document, may be a
globaldocument or a writer-document with linked sections.
I'm not sure, what would be the better way to include such a function, if by the
possibility of 'save section as new document/save section-changements to
source-document' or the option 'save changes to linked documents' by saving a
globaldocument, perhaps your specialists have also better ideas.

I would like to add a further proposition, that normally would be an issue for
sCalc spreadsheets. But it concerns the same funcitonality as the description of
the sections in writer:
in sCalc you also might have tables that are links to tables of different
spreadsheets. Also here I found it very helpfull, if I could save changes to the
 source-spreadsheet.
Thanks a lot,
