[Feature] Advanced User Experience & Interface Design System

[Avtrkrb]

Description

Implement comprehensive user experience and interface design capabilities to enhance Nanocoder's interface sophistication and user interaction patterns. Currently, Nanocoder has basic UI components with simple text-based displays and limited interface customization. The system needs advanced UI components, responsive design capabilities, theme customization, adaptive interaction patterns, and intelligent interface adaptation to match industry-leading CLI coding agentic tools.

The feature will implement:

• Advanced UI component library with responsive design capabilities
• Component-based UI framework with theme customization
• Adaptive interaction patterns with context-aware features
• Intelligent interface adaptation with multi-modal input handling
• Advanced navigation systems with context-aware adaptation

Use Case

Current Problem:

• Basic UI components with limited styling options
• No responsive design for different terminal sizes
• Static interface without theme customization
• Simple interaction patterns without context awareness
• Basic navigation without advanced features

Target Scenarios:

1. Responsive UI: Interface adapts to different terminal sizes and layouts
2. Theme Customization: User-configurable interface themes and styling
3. Context-aware Interactions: Interface adapts based on conversation context
4. Advanced Navigation: Multi-level navigation with history management
5. Intelligent Adaptation: Interface learns and adapts to user preferences

Proposed Solution

Phase 1: Foundation - UI Component Library (2-3 weeks)

• Implement advanced UI component system with enhanced styling
• Add responsive design capabilities with breakpoint management
• Create AdvancedMessageBox and other enhanced components
• Implement ResponsiveLayout system with adaptive layouts
• Maintain backward compatibility with existing UI components

Phase 2: Interface Framework - Component-based UI System (3-4 weeks)

• Create UIComponentFramework for component management
• Implement ThemeSystem with customization capabilities
• Add theme registration and application system
• Create component registry with dynamic loading
• Enhance with advanced layout management features

Phase 3: User Experience - Adaptive Interaction Patterns (4-5 weeks)

• Implement AdaptiveInteractionManager for pattern selection
• Add ContextAwareInput with intelligent suggestions
• Create interaction pattern registry with context analysis
• Implement multi-modal input handling
• Add interaction history and learning capabilities

Phase 4: Advanced UX - Intelligent Interface Adaptation (3-4 weeks)

• Create AdvancedNavigationSystem with history management
• Implement IntelligentInterfaceAdapter with learning
• Add navigation stack with back/forward functionality
• Create adaptation strategy selection and learning
• Enhance with user preference integration
