Recently I got an email asking for a trimmed down English-only version of WinDirStat. To be honest I was quite flabbergasted and upset. After all both developers involved in WinDirStat are native Germans, so why not make it a light version that is German-only? I think everyone knows and accepts that English is the lingua franca of the modern world, but by the number of speakers you shouldn’t underestimate Mandarine either. The author of said mail had an English name so we can safely assume he was a native speaker of English. But why the assumption that a light version (he was referring to PortableApps as well) has to be English?
In fact besides the <Unknown> issue the translations were the next biggest issue for me. Why? Because the current system doesn’t allow users to translate themselves and maintain those translations independently from a developer who will have to link the resource DLL for that language. This is something that needs fixing, not the availability of those languages in the installations.
So, sorry. For the moment I’m not up for such an English-only light version. But after all it’s OpenSource … patches are welcome. But then there are these more pressing issues which really ask for patches …
