I wonder whether anybody has come accross some kind of plugin/extension/… for Jupyter Notebooks that would allow Markdown cells to be in several languages, e.g. English and German? When I google that, I only get responses for several programming languages, not natural languages. With a switch on the top the reader could change between the two (or even more) languages as it is common practice for many webpages. Such a feature would make it much easier to use Jupyter Notebooks in mixed groups where people have different mothertongues. Currently I maintain several Jupyter Notebooks in parallel - the programming code is the same, the Markdown cells differ.
