# UI.py Refactoring Record
## Overview
This document tracks the complete refactoring process of the monolithic UI.py file (3,345 lines) into a modular, maintainable project structure.
## Project Analysis
### Original Structure
- **File**: `UI.py` (3,345 lines)
- **Total Classes**: 15 major classes
- **Main Components**: Styling, Node definitions, UI components, Main windows, Dialogs, Application entry
### Identified Issues
1. **Monolithic Structure**: All code in single file
2. **Mixed Concerns**: Business logic, UI, and styling intermingled
3. **Poor Maintainability**: Difficult to navigate and modify
4. **No Separation**: Hard to test individual components
5. **Collaboration Challenges**: Multiple developers working on same file
## Refactoring Plan
### Target Structure
