Immediate clarity: where the classic command is terse, v13 uses just enough visual scaffolding to answer the questions you always ask yourself while building a quick socket session. Who’s listening on the other end? Which port did I bind? Is this TCP or UDP? Has data flowed since I typed that last payload? The GUI answers those in one glance: connection tiles show peer info, a live byte counter and rate graph track throughput, and a timestamped hex/plaintext toggle reveals the exact stream semantics. That saves the sort of micro‑cognitive trips that add up during repeated ad‑hoc testing.
