protocol with metadata (name, size, data) - Multi-file sharing under single hash with dynamic file list updates - Download functionality for both WASM and native platforms - Real-time file synchronization without node restart UI/UX Improvements: - Scrollable interface with protected footer - White text on all colored buttons for better visibility - Reorganized layout: Share button moved to Shared Files section header - Added Close Sharing button to stop sharing sessions - Added Refresh Files button to fetch newly added files dynamically - Improved button positioning and spacing for better accessibility Core Functionality: - Dynamic file list updates without changing node hash - Round-robin file distribution system (modified to send all files per connection) - Duplicate file detection on refresh - Automatic file info cleanup when closing sharing session - Error handling with proper status messages on timeout/failure Technical Changes: - Modified Echo protocol to send all files in single connection - Added shared_files reference to EchoNode for dynamic updates - Implemented reconnect_for_files() for on-demand file refresh - Enhanced error reporting in receive status - Removed unnecessary "Sent X bytes" log messages Bug Fixes: - Fixed hash display when files are added dynamically - Fixed footer being overwritten by scrollable content - Fixed status stuck on "Refreshing files..." on timeout - Fixed file list not updating in same session --- p2p-transfer/src/app.rs | 769 +++++++++++++++++++++++++++++++++++---- p2p-transfer/src/node.rs | 184 ++++++++-- 2
