Im thinking about creating a new set of BIFs, same for all languages - the files different to language will be moved into override (FYI its only character set images and in german translation there is a different credits that includes translator's team).
That would spared about 300mb of duplicated content that is outdated and increased efficiency of module loading - less to load less to overwrite.
Also it would make things easier for anyone attempt to make anything with BIFs - as currently such person must make a different version for each language.
Got one problem though - so far there isn't any BIF extrator/updater I could use for this so I guess I would have to distribute all modified bif files as I am not skilled enough to create such tool myself.
opinions, suggestions?
