diba,
The way Launcher is built its impossible to localize anything except the word "Launcher" for sure. That's because Launcher itself doesn't contain any other strings...
We could only create locale-aware extensions, which could be quite easy (especially if yifanlu would got my suggestion implemented in his Launcher... btw,
yifanlu, I'm quite happy with this json-stdout stuff, and making it locale-aware is just a piece of cake, which cannot be said for simple json extensions... why don't you integrate it, man?
