I've been using DeepL translator for a while, and it has in my experience been fantastic. My suggestion is to somehow integrate DeepL's API into Crow translate, so that one could choose between Google/Bing/Yandex/DeepL.
Ditto, and we already discuss this. This must be done on QOnlineTranslator side. Also, there is already Lingvo and LibreTranslate, you forgot to mention this :)
