I was wondering, is there a way to delete my vocabulary for a language, but preserve my imports for that language?
Go to vocab page, set items per page to 200, mark all, then delete all, then go to next page until the last.
That would affect only Yellow words, and actually, would prevent them being recognized again. They would just appear white.
I want a clean slate with a language. All blue.
@creimann - In that case it is not possible to do this without removing your imported lessons as well. Instead of resetting everything, I would encourage you to just highlight and save any known words that you don’t know the meaning for.
