        So a quick answer with some small ideas:

                        Would be nice ( even better if we can support header and footer)

                        Supporting group in Writer can also be nice...

                        I tried to add limited support for charts for Spreadsheet, but this is very 
complicated
                        ( and I am not fully sure that I have chosen the good interface ) ;
                        note that this also implied to add support to create formula, ...

                        Can be nice, but I do not know if this is really important… 

                        In fact, when I last worked on libodfgen, I added code to export settings 
in all generators
                         ( but mainly to make these classes behaviors more identical )

                       Normally, these functions have already been dropped. 

                        But this problem is more general, i.e. we have many define functions, some 
are implemented, 
                        but I am not sure that all these functions are implemented ...

                         We would probably need to add it latter, but not now ( and this seems a 
very complex task )

        Potential ideas:
                . Is it better if we make all interface inherit from a basic generic interface ?
                . Do we need to add some numbering styles interfaces in text, … (i.e. functions 
which allows to define
                a number/date/time format ) ? Idem for formula
                . If the interface for presentation need also chart, do we need to add a 
RVNGChartInterface and some
                mechanism to obtain access to this interface in 
RVNGPresentation/SpreadsheetInterface
