QuickMind v2.2.0 Release Notes

🎉 Major Release: Advanced Spaced Repetition & Anki Import

This is a significant update that transforms QuickMind from a basic flashcard app into a sophisticated spaced repetition learning system comparable to Anki.

🚀 New Features

🎯 Advanced Spaced Repetition Algorithm (SM-2+)

  • Multi-step Learning Process: New cards now progress through configurable learning steps
  • Relearning System: Failed cards automatically enter relearning cycle
  • Leech Detection: Automatically identifies and suspends problematic cards (8+ failures)
  • Interval Fuzzing: Randomizes intervals by ±25% to prevent card clustering
  • Flexible Algorithm Settings: Customize learning steps, graduating intervals, and more

📊 Enhanced Rating System

  • 4-Point Rating Scale: Replaced 6-button system with intuitive Again/Hard/Good/Easy
  • Color-Coded Buttons: Red (Again), Orange (Hard), Green (Good), Blue (Easy)
  • Adaptive Intervals: Smart interval calculation based on card difficulty and performance

📥 Comprehensive Import System

  • Anki JSON Import: Import exported Anki decks seamlessly
  • CSV File Support: Import from Excel/Google Sheets with customizable columns
  • Text File Import: Support for various text formats with configurable separators
  • Batch Import: Import hundreds of cards at once with progress tracking

📈 Advanced Statistics & Analytics

  • Daily Dashboard: Cards due today, studied, and completion rates
  • Topic-based Statistics: Detailed progress tracking per subject
  • Learning History: Comprehensive session statistics and trends
  • Performance Metrics: Success rates, average intervals, and difficulty analysis

🎨 Improved User Interface

  • Responsive Design: Better layout adaptation for different screen sizes
  • Enhanced Study Mode: Cleaner interface with improved card presentation
  • Import Dialog: Dedicated interface for file imports with preview
  • Visual Feedback: Better animations and state transitions

🌍 Enhanced Localization

  • Complete Russian Translation: All new features fully localized
  • Chinese Language Support: Extended translations for new components
  • Dynamic Language Switching: Instant interface updates when changing languages

🔧 Technical Improvements

🏗️ Architecture Enhancements

  • Dependency Injection: Proper DI container setup with Microsoft.Extensions.DependencyInjection
  • Service Layer: Dedicated services for spaced repetition, import, and card management
  • Database Migrations: Automatic schema updates with new fields for algorithm support

📊 New Data Model

  • Extended Card Properties: Added CardType, LearningStep, Lapses, IsLeech, IsSuspended
  • Algorithm Fields: Interval, Repetitions, EaseFactor, DueDate, FuzzFactor
  • Learning Tracking: LearningDueDate, GraduatingInterval, EasyInterval

🛠️ New Services

  • SpacedRepetitionService: Complete implementation of SM-2+ algorithm
  • AnkiImportService: Handles various import formats and data validation
  • Enhanced CardService: Extended with topic management and advanced statistics

🐛 Bug Fixes

  • Study Session Completion: Fixed issue where study sessions wouldn't end properly
  • Card Movement: Resolved kanban board not updating card positions correctly
  • UI Responsiveness: Fixed rating buttons overlapping on smaller screens
  • Database Consistency: Improved data integrity and migration handling

📱 User Experience Improvements

  • Intuitive Study Flow: Streamlined learning process with clear visual feedback
  • Better Card Management: Enhanced drag-and-drop functionality between columns
  • Import Workflow: User-friendly import process with error handling and validation
  • Performance Optimization: Faster card loading and smoother animations

🔄 Migration Notes

  • Database Auto-Migration: Existing cards automatically upgraded to new schema
  • Settings Preservation: All user preferences maintained during update
  • Backward Compatibility: Existing study data preserved and enhanced

📦 Installation

  • Windows: QuickMind-Setup-v2.2.0.exe (34.2 MB)
  • Automatic Updates: Existing installations will be notified of available update
  • Clean Installation: Fresh installs include all new features by default

🎓 Learning Algorithm Details

The new SM-2+ algorithm includes:

  • Initial Learning: 1m, 10m intervals for new cards
  • Graduating Interval: 1 day for cards completing learning
  • Easy Interval: 4 days for cards rated as "Easy"
  • Maximum Interval: 36,500 days (100 years) limit
  • Leech Threshold: 8 failures before card suspension

🔮 Coming Soon

  • APKG Import: Direct Anki package file support
  • Advanced Statistics: Detailed learning analytics and progress charts
  • Custom Themes: Additional color schemes and customization options
  • Sync Functionality: Cloud synchronization across devices

Full Changelog: v2.1.2...v2.2.0
