After reading this thread
I thought I might just start to translate because I had some free time left. Now I've only done the translation, without the implementation, what should we do from here? Would anyone like to make a multilingual Welcome! Notebook possible? According to @laurent it should not be the hardest thing to do, but I don't know how to do it (yet)...
My forked PR with the files: German translation of the Welcome! Notebook by Mr-Kanister · Pull Request #6 · Mr-Kanister/joplin · GitHub
