Before this post gets too out of control, could I ask that general feedback about the feature is held off until the general announcement is made sometime next week? I really want to make sure I can listen to and help the developers, and while your feedback is appreciated I want to have this post focused on the development side of this topic.
I do want to address the sentiment of these 2 posts though.
Like I said, I started work on this last year, and this feature has actually been completed (from a development perspective) for sometime. We held the feature back because we realised that it would not be well received at the time it was completed. Delivering this feature now clears the path to focus on delivering the features that people are missing from the old summary pages. You can follow along here for updates on that topic. I just want to assure you that we are all busy working on improving Wanikani for all users, and releasing this feature now is so we can keep the proverbial house clean and not cluttered with undelivered or half done features.
