• Intelligent File Picker: Use # anywhere in your message for file selection with auto-completion and browser popup
• Double Ctrl+C Exit: Press Ctrl+C twice within 2 seconds to gracefully exit the chat session

💡 How Auto-Completion Works:

• Type / → All available commands appear automatically
• Type /c → Filters to commands starting with 'c' (clear, cls, clear-screen, etc.)
• Type /temp → Shows /temperature command
• Type /think → Shows /thinking and /thinking-mode commands

💡 How File Picker Works:

• Type # anywhere in your message to open the file picker
• Choose files interactively (with icons for file types)
• Insert filenames naturally into your prompt, e.g., examine #test.py and check for errors
• File picker works anywhere in your message, not just at the beginning

💡 How to Exit:

• Press Ctrl+C once → Shows "Press Ctrl+C again to exit" message
• Press Ctrl+C again within 2 seconds → Gracefully exits the chat
