 ## Recent Changes
-1. Resource Management Optimization:
+1. Implemented Continuous Board Monitoring:
+   - Added separate monitoring and capture tasks:
+     * Monitor constantly checks for chess boards (0.5s interval)
+     * Capture processes frames when active (0.1s interval)
+   - Auto-capture behavior:
+     * Starts monitoring when app launches
+     * Automatically starts capture when board appears
+     * Stops capture (but keeps monitoring) when board disappears
+     * Resumes capture when new board is detected
+   - Fixed image conversion pipeline:
+     * Proper NSImage → CGImage → CIImage conversion
+     * Efficient resource management
+     * Clean error handling
+
+2. Enhanced Status Indication:
+   - Visual status indicator shows capture state:
+     * Green: Actively capturing board
+     * Yellow: Waiting for board
+     * Gray: Not capturing
+   - Clear error messages for different states
+   - Automatic status updates based on board detection
+
+3. Resource Management Optimization:
    - Implemented shared CIContext pattern:
      * Prevents command queue exhaustion
      * Reduces Metal resource usage
