What happened to half-hearts?
A while ago, it was possible to recover half a point if a mistake was corrected. That feature was great. What happened to it or is it only for learners below a certain level?
It was found that half-hearts actually made fewer people stay and learn, so they've been disabled for. There is currently a test group which has them again, though, so they might come back in the future.
The half hearts really encouraged me more! It also made me look at my mistakes closer. I hope they bring them back!
