Hi Joachim,
Thanks for the feedback. I am not surprised that the translation needs work. Part of the issue is that English terminology doesn’t always have a direct match in other languages (and sometimes the reverse – English does not differentiate between two concepts that other languages do).
Since you offered :-), I would ask that you consider correcting the errors in the German keywords that are supplied with the app, rather than the one you have built for yourself. I can then replace the file for the next release of the app.
I did use Google in this case, though I have used DeepL in other situations. In this case, I ran into some issues with DeepL and I could tell that some of the translations from DeepL were incorrect, so I went with Google.
