Architecture Improvements

Connection Status

The connection status indicator provides immediate visual feedback about the WebSocket connection state, helping users understand if their terminal is actively connected to the server.

Export Functionality

The export feature allows users to save terminal session output for documentation, debugging, or sharing purposes. The implementation reads the entire terminal buffer and formats it as plain text.

User Experience Enhancements

Visual Feedback: Connection status is always visible in the toolbar
Export Workflow: Simple menu action → Share sheet → Save/Share options
File Naming: Exported files include session name and timestamp

Technical Implementation

Buffer Content Extraction

The getBufferContent() method in TerminalHostingView.Coordinator:

Iterates through all terminal rows
Extracts characters from each column
Trims trailing whitespace
Returns formatted text content

Uses native iOS UIActivityViewController wrapped in SwiftUI:

Temporary file creation in app's temp directory
Automatic cleanup after sharing
Support for all iOS sharing destinations

Future Enhancement Ideas

Haptic Feedback: Add subtle haptics for terminal interactions (already has HapticFeedback utility)
iPad Keyboard Shortcuts: Command palette, quick actions
Improved Error Messages: User-friendly error descriptions with suggested actions
WebSocket Optimization: Better reconnection strategies, connection pooling
Session Templates: Save and reuse common session configurations
Multi-Window Support: iPad multitasking with multiple terminal windows

The iOS app now exceeds feature parity with the web version and includes native platform enhancements that improve the mobile terminal experience.
