UART sniffing is incredibly primitive and could really stand to have some more features. Even the ancient HP4957 could separate Tx and Rx visually, Waveforms still can't do that. And maybe timestamping? Would that be nice? Yes.
Also "scope" (ancient Greek σκοπέω) has a pretty broad meaning of "to look, look at, behold; examine, inspect"[1] (gyroscope, stethoscope, horoscope etc).

Alas, I spent it all on oscilloscopes, function generators, and power supplies!
