As I said the package is in edge channel and marked as private. It is still not ready to be published, I have other problems, e.g. when using gtk2 file system dialogs applications hang on “File/Save as” dialog (if you have access to the package you can try this by yourself - install it, open an app from command line and try to save the file), have problems with document icons and file associations (to make applications default for supported document types) etcetc.
The folder /etc/SoftMaker is needed to keep some common data, e.g. hunspell dictionaries which users download. When one user of multiuser system downloads a dictionary it is stored in this place, and other users can use it too.
In Windows we use c:\programdata folder for this purpose. In Linux we had to create such a folder in /etc in our post-install script from .deb package. This was done due to customer requests and IMO is good to be kept.
