Thanks for this! It's nice to see more tools out there for advanced language learners because, like the article states, it sure is a long slog isn't it. I especially am happy to see that this app adds the Lemma https://en.wikipedia.org/wiki/Lemma_(morphology) of the new vocabulary to the spaced-repetition flashcards rather than the particular form it appears in on the page. That has taken up a lot of my time with other similar apps.
