Is it possible to add KOffice-wide options that:
- can be used also in filters
- have a nice user interface in each KOffice application

My problem is about saving a UTF-8 XML file from QDomDocument. There are two 
possibilities:
- by QCString (fast but uses rougly twice as much memory (or perhaps even more 
as I have not checked what KZIp and lower do.))
- by QTextStream (roughly twice as slow but low need of memory)

(Yes, I know that QTextStream is used even in the case of QCString, but 
QTextStream on a QString and then QString::utf8 are much faster than a direct 
UTF-8 QTextStream.)

The QCString way is used by KoDocument while the QTextStream way is used by 
some KWord filters. I would like to unify that but by giving the choice 
between the 2 solutions.

I suppose that user would prefer the faster solution but the problem are very 
long documents. If a user cannot save its document because the computer does 
not have again the same memory amount, it is a big problem. So I would like 
to allow the user to choose what method is used. (I do not think that an 
automatical solution would exist and it would have probably annoying 
border-cases.)

Have a nice day!

PS. 1: another candidate for global settings is the always-fast setting in 
KoPicture that has no user interface.

PS. 2: what very long documents are is relative. Depending on the computer, it 
might be already a document of 1MB lsize. But if I remember well, some users 
wanted to load text files of 20MB or even more. In any case, there will 
always be users that need to use documents that barely fit the memory and 
computing power of their computer. I would like that such users fells more 
welcome than now on KOffice (as much as possible.)
