## Description

Master the Technical Interview with Discipline and Data.

Green Timer is the ultimate productivity hub designed specifically for LeetCode. Move
  beyond simple time-tracking and transform your practice into a data-driven journey.
  Designed with a sleek "Glass-Terminal" aesthetic, Green Timer provides the professional
  environment you need to build consistency and solve with speed.

⏱️ INTELLIGENT TRACKING
   * LeetCode Auto-Detection: Automatically captures the problem name and number as you
     browse LeetCode.
   * Smart Automation: Opt-in to auto-add problems and auto-start timers the moment you
     land on a question.
   * Custom Status Manager: Define your own journey with color-coded statuses like "Hint
     Assisted," "Struggled," or "Mastered."
   * Multi-Timer Management: Solving multiple problems? Manage several independent
     stopwatches simultaneously.

📈 DEEP PERFORMANCE ANALYTICS
   * Problem-Specific Deep-Dives: Click the analytics icon on any question to see your
     solving speed trends over multiple attempts.
   * Visual Insights: Beautiful line charts visualize your progress, alongside automated
     metrics for Average Speed and Personal Best.
   * Yearly Activity Heatmap: Track your consistency with a GitHub-style contribution
     heatmap.
   * Daily Goals & Streaks: Set targets and visualize your progress with live-updating goal
     indicators.

🏷️ SMART TAGGING SYSTEM
   * Centralized Metadata: Tags are linked to the problem, not just the attempt. Categorize
     a problem once, and it stays synchronized across your entire history.
   * Multi-Select Filtering: Powerful "AND" logic filtering allows you to find specific
     practice sets (e.g., "Hard" + "Dynamic Programming") instantly.
   * Tag Distribution: Visualize your most practiced categories and drill down into them
     with a single click.

🎨 PREMIUM UI/UX
   * Glass-Terminal Design: A high-contrast, distraction-free interface optimized for long
     coding sessions.
   * Instant Theme Switching: Toggle between Glass-Dark (#00ff00) and Terminal-Light
     (#008000) modes instantly.
   * Responsive Dashboard: Access your full data suite via the extension popup or the
     immersive full-page dashboard.

🛡️ PRIVACY BY DESIGN
  We believe your study data is yours alone. Green Timer is a zero-leak extension:
   * 100% Local Storage: All data lives exclusively in your browser.
   * No Accounts Required: No sign-ups, no tracking, and no third-party servers.
   * Secure & Open: Built with Manifest V3 and secure DOM manipulation for maximum safety.
