Future Enhancements

Future Enhancements

This document describes planned future enhancements for Toss. These features are not currently in the MVP scope but are documented for future implementation.

22. Clipboard Streaming

Overview

Real-time clipboard streaming for rapid clipboard changes. Instead of sending complete clipboard content on each change, stream incremental updates.

Design Considerations

Protocol Design:

• Streaming protocol over QUIC or WebSocket
• Change rate limiting to prevent spam
• Conflict resolution for simultaneous changes
• Optimize for low latency (under 100ms)

Implementation Approach:

1. Detect rapid clipboard changes (e.g., typing)
2. Buffer changes and send in batches
3. Use delta compression for text changes
4. Implement backpressure handling

Files to Create:

• rust_core/src/protocol/streaming.rs - Streaming protocol
• rust_core/src/network/streaming.rs - Streaming transport
• flutter_app/lib/src/core/services/streaming_service.dart - Flutter streaming client

Dependencies:

• Core sync working
• Network protocol stable
• Performance optimization needed

23. Selective Sync

Overview

Allow users to choose which devices receive clipboard updates. Enable per-device sync settings and device groups.

Design Considerations

UI Components:

• Device selection UI in settings
• Per-device sync toggle
• Device groups/tags
• Sync filters (text only, images only, etc.)

Implementation Approach:

1. Add sync_enabled flag to device storage
2. Update network broadcast to filter by device settings
3. Add device groups/tags to storage schema
4. Create UI for managing sync preferences

Files to Create:

• rust_core/src/storage/device_storage.rs - Add sync settings
• flutter_app/lib/src/features/settings/device_sync_settings.dart - UI component
• flutter_app/lib/src/core/models/device_sync_preferences.dart - Data model

Dependencies:

• Device management (#2)
• Settings UI
• Network broadcast logic

24. Team/Organization Support

Overview

Shared clipboard groups for teams and organizations. Enable multiple users to share clipboard within a team.

Design Considerations

Data Model:

• Team/Organization entities
• Role-based access (admin, member, viewer)
• Group management
• Invitation system

Implementation Approach:

1. Design team/organization database schema
2. Implement group management API
3. Add role-based access control
4. Update relay server for group messaging
5. Create team UI components

Files to Create:

• rust_core/src/storage/team_storage.rs - Team storage
• rust_core/src/crypto/team_auth.rs - Team authentication
• relay_server/src/api/teams.rs - Team API endpoints
• flutter_app/lib/src/features/teams/ - Team UI

Dependencies:

• Core features complete
• Relay server
• Authentication system

25. Browser Extension

Overview

Web-based clipboard access via browser extension. Enable clipboard sync from web browsers.

Design Considerations

Architecture:

• Chrome extension (Manifest V3)
• Firefox extension (WebExtensions API)
• WebSocket connection to relay server
• Handle browser clipboard API limitations

Implementation Approach:

1. Design extension architecture
2. Implement Chrome extension
3. Implement Firefox extension
4. Add WebSocket client for relay connection
5. Handle browser clipboard restrictions

Files to Create:

• browser_extension/chrome/ - Chrome extension
• browser_extension/firefox/ - Firefox extension
• browser_extension/shared/ - Shared code

Dependencies:

• Relay server
• WebSocket support
• Browser API knowledge

26. Conflict Resolution

Overview

Handle simultaneous clipboard changes from multiple devices. Resolve conflicts when multiple devices change clipboard at the same time.

Design Considerations

Resolution Strategies:

• Timestamp-based (last write wins)
• User preference (device priority)
• Manual resolution UI
• Conflict notifications

Implementation Approach:

1. Design conflict detection algorithm
2. Implement timestamp-based resolution
3. Add user preference for resolution strategy
4. Create conflict notification UI
5. Allow manual conflict resolution

Files to Create:

• rust_core/src/protocol/conflict.rs - Conflict resolution
• flutter_app/lib/src/core/services/conflict_service.dart - Conflict handling
• flutter_app/lib/src/features/conflicts/ - Conflict UI

Dependencies:

• Core sync working
• Network events
• UI components

27. Content Compression

Overview

Reduce bandwidth for large clipboard content. Compress clipboard data before transmission.

Design Considerations

Compression Library:

• Use zstd (fast, good compression ratio)
• Compress only large content (>1MB)
• Add compression settings
• Optimize for mobile networks

Implementation Approach:

1. Add zstd dependency
2. Implement compression for large content
3. Add compression settings to UI
4. Test compression ratios
5. Optimize for mobile networks

Files to Create:

• rust_core/src/protocol/compression.rs - Compression utilities
• rust_core/Cargo.toml - Add zstd dependency
• flutter_app/lib/src/features/settings/compression_settings.dart - UI

Dependencies:

• Message protocol
• Settings system

Implementation Priority

These enhancements are not in the current MVP scope. Priority would be:

1. Content Compression (#27) - Most practical, immediate benefit
2. Selective Sync (#23) - User-requested feature
3. Conflict Resolution (#26) - Important for multi-device scenarios
4. Clipboard Streaming (#22) - Performance optimization
5. Browser Extension (#25) - Expands platform support
6. Team/Organization Support (#24) - Enterprise feature, most complex

Notes

• All future enhancements depend on core MVP features being stable
• Some features may require relay server updates
• UI components should follow existing design patterns
• Consider backward compatibility when implementing
