New users can easily understand the concepts of ports, listeners, and IP addresses without fearing syntax errors.

Single window for IP, Port, and File Path.

Better thread management prevents the GUI from freezing during high-bandwidth data transfers or prolonged listening states.

You can establish an instant, unencrypted communication channel between two machines. One user sets the GUI to listen on a port, and the other connects to that IP address. Any text typed into the console appears on the other screen instantly. Local File Sharing
