This is pretty sweet, even though I am years behind.
I just wondered whether the short reports could not also made a bit more verbose, by adding:
total number of packets (EDIT: this is what the total field already reports, sorry)
total number of bytes (this seems still useful)
number of dupACKs (as estimate of loss/reordering)
number of ECT(0) packets (mainly as debugging aid, to find flows doing funny things...)
full 5 tuple of the flow

Nonce sum may be useful to know about.

"I'd like to see a sequence plot with the ECN codepoint indicated by colour coding, and similarly for ECE/NS/CWR on the ack path." -Jon

"I'd like to see a dynamic estimate of cwnd (or rather, in-flight data), with similar colour coding and/or labelling, for correlation." -Jon

When following the instructions go complained about 'go get" being not supported any more, however go install seems to work...

go: go.mod file not found in current directory or any parent directory.
'go get' is no longer supported outside a module.
To build and install a command, use 'go install' with a version,
like 'go install example.com/cmd@latest'
For more information, see https://golang.org/doc/go-get-install-deprecation
or run 'go help get' or 'go help install'.
