A good add-on for anyone who is learning a language and doesn't have time nor energy to set up many different add-ons for language learning. it's got all you'd ever want in one place. i definetely reccommend going through all settings after you've used the add-on for some time since there are many hidden featues that could make your learning even more convienient. it's even got gamification for those who need achievements and exp as motivation. ofc there's always room for improvement but seeing how this app has changed within last 3 months one can only expect for it to get even better with time
