+#### 🎲 Seed History
+Advanced seed tracking with interactive history management and UI.
+
+- **Automatic Tracking**: Monitors all seed changes with timestamps
+- **Interactive History**: Click any historical seed to reload instantly
+- **Smart Deduplication**: 500ms window prevents duplicate rapid additions
+- **Persistent Storage**: History survives browser sessions and ComfyUI restarts
+- **Auto-Hide UI**: Clean interface that hides after 2.5 seconds of inactivity
+- **Visual Feedback**: Toast notifications and selection highlighting
+
+**Use Cases:**
+- Track promising seeds during creative exploration
+- Quickly return to successful generation parameters
+- Maintain reproducibility across sessions
+- Compare results from different seeds efficiently
+
