Anki add-on: Wrong Answer Stat Tracker

Wrong Answer Stat Tracker is designed to pinpoint your weakest study areas by tracking your review history and ranking your most frequently missed cards. You can view your mistake counts organized by either specific tags or broader decks, filter the data by custom time frames, and narrow the list down using a parent tag filter. Plus, you can double-click any card in the list to instantly open it in the Anki Browser for a quick edit or review :)
