Enhancement: Expand Save Tips Feature with Advanced Management Capabilities

[DevinByteX]

📋 Feature Description

Enhance the existing save tips feature with additional functionality to improve user experience and tip management capabilities. Currently, the app has basic tip saving functionality with filters and search. This enhancement aims to add more comprehensive features for power users.

🎯 Current Implementation

The app currently has:

• ✅ Basic save tip functionality (useSaveTip.ts)
• ✅ Saved tips list with search and filters (SavedTipsScreen.tsx)
• ✅ Individual tip detail view (SavedTipDetailScreen.tsx)
• ✅ Tip deduplication (prevents saving identical calculations)
• ✅ Delete individual tips and clear all tips
• ✅ Filter by percentage (0-10%, 10-15%, 15-20%, 20%+)
• ✅ Filter by people count (1, 2-4, 5+)
• ✅ Filter by date (today, week, month)

✨ Proposed Enhancements

1. Export & Backup

• Export saved tips as CSV/JSON for data backup
• Bulk export with date range selection
• Import previously exported tips data

2. Tags & Categories

• Add custom tags to saved tips (e.g., "Restaurant", "Delivery", "Bar")
• Create custom categories for organizing tips
• Filter tips by tags/categories
• Tag suggestions based on tip amount or percentage

3. Statistics & Analytics

• Monthly/weekly tip spending overview
• Average tip percentage calculation
• Most frequent tipping patterns
• Charts for visualizing tip trends over time
• Compare spending across different time periods

4. Edit Saved Tips

• Allow users to edit saved tip details (add notes, modify tags)
• Add custom notes/descriptions to saved tips
• Update tip details if calculation was incorrect

5. Quick Actions

• Share saved tip directly from list view
• Duplicate tip calculation for quick reuse
• Favorite/pin important tips to top
• Swipe actions for quick delete/share

6. Smart Features

• Tip reminders for recurring expenses
• Suggest tip percentage based on user history
• Detect unusual tipping patterns
• Group related tips (e.g., same restaurant visits)

🛠️ Technical Considerations

• State Management: Extend SavedTip interface in context/types.ts to include new fields (tags, notes, categories, favorites)
• Storage: Ensure AsyncStorage can handle larger data sets efficiently
• Performance: Implement pagination or virtualization for large tip lists
• Migration: Handle schema migration for existing saved tips
• File Export: Use react-native-fs or similar for file operations

📦 Dependencies (Potential)

• react-native-fs - for file export/import
• react-native-chart-kit or victory-native - for statistics visualization
• Native date pickers for date range selection

🎨 UI/UX Considerations

• Maintain current clean, intuitive design
• Add minimal UI elements that don't clutter the interface
• Use existing color themes and design patterns
• Ensure new features are discoverable but not intrusive

📱 Platform Support

• Should work on both iOS and Android
• Test with different screen sizes
• Ensure export/import works with platform-specific file systems

• Performance remains smooth with 100+ saved tips
• Data integrity is maintained during export/import
