+# Pull Request - Add Logging and Enhanced Metadata Features
+
+## Summary
+
+Adds logging system and enhances metadata processing for Flut Renamer.
+
+## Key Changes
+
+1. **New Logging System** (`lib/tools/logger.dart`)
+   - Singleton logger with real-time log streaming
+   - Timestamped log entries with stream support
+
+2. **Enhanced Metadata Handling** (`lib/tools/file_metadata.dart`)
+   - Added OS:UUID and OS:RandomString metadata fields
+   - Improved error handling and tag detection regex
+
+3. **Updated Replace Rule** (`lib/rules/rule_replace.dart`)
+   - Added {RandomString} tag support (8-digit random string)
+   - Enhanced tag detection and parsing
+
+4. **Dependency Update** (`pubspec.yaml`)
+   - Added uuid: ^4.4.0 package for UUID generation
+
+## Benefits
+
+- Real-time operation feedback via logs
+- More robust metadata extraction with error handling
+- New powerful metadata fields for flexible renaming
+- Auto-generate random strings for unique filenames
+
+## Compatibility
+
+All existing functionality remains intact. New features tested across platforms.

+# Pull Request - Feature Enhancements and Improvements
+
+## Description
+
+This PR introduces several significant improvements to the Flut Renamer application, enhancing both functionality and robustness.
+
+## Key Features and Enhancements
+
+### 1. Logging System
+- Added a new `Logger` class in `lib/tools/logger.dart` that provides real-time logging capabilities
+- Implements singleton pattern for global access
+- Supports live log streaming for UI feedback
+- Includes timestamped log entries with clear formatting
+
+### 2. Enhanced Metadata Processing
+- Improved `FileMetadata` class in `lib/tools/file_metadata.dart`
+- Added comprehensive error handling for metadata extraction
+- Enhanced metadata tag detection regex to support underscores and other characters
+- Added support for `OS:UUID` and `OS:RandomString` metadata fields
+
+### 3. Improved Replace Rule
+- Enhanced `RuleReplace` class in `lib/rules/rule_replace.dart`
+- Added automatic `{RandomString}` tag replacement with 8-digit random alphanumeric strings
+- Improved metadata tag detection and parsing
+- Added error handling for tag processing failures
+
+### 4. New Dependency
+- Added `uuid: ^4.4.0` dependency for UUID generation
+- This enables reliable and unique identifier creation for files
+
+## Changes Made
+
+- Created `lib/tools/logger.dart` - new logging system
+- Modified `lib/tools/file_metadata.dart` - enhanced metadata processing
+- Modified `lib/rules/rule_replace.dart` - improved replace rule functionality
+- Updated `pubspec.yaml` - added uuid dependency
+
+## Benefits
+
+- Provides users with real-time feedback on renaming operations via log messages
+- Increases application robustness with enhanced error handling
+- Adds new powerful metadata fields for more flexible renaming
+- Improves user experience with automatic random string generation
+
+## Testing
+
+All existing functionality remains intact, and the new features have been tested for compatibility across platforms. The application continues to support all existing renaming rules while adding the new enhancements.
+
+## License
+
+This contribution adheres to the existing project license.
