Hello Fruhulda,
programming is a little more complex than that, ie. the hard features LibreOffice 4.2 where freezed at the beginning of november ( see https://wiki.documentfoundation.org/ReleasePlan/4.2 ) and now LibreOffice 4.2 is mainly in the phase of bug corrections...
Currently the parent's library of libmwaw: librevenge is rewritten and allows now to export spreadsheet, I am trying to add some spreedsheet filters (for some easier format) in libmwaw: for BeagleWorks/WordPerfect suite, Microsoft Works, ... ( so these filters will probably appear in LibreOffice 4.3 ).
After I will need to create the classes needed to export true pictures (ie. no longer create a text document with some embedded graphics), then I will be able to rewrite differently the AppleWorks/ClarisWorks filters to convert more kind of documents.
So if all go smooth, it may appear in LibreOffice 4.3, if not (the most probable), in LibreOffice 4.4.
