oooh fantastic. Thanks! Exciting

My initial test looks pretty good, seems I will need to muck around a bit to get to "one click runs the simulation and displays the trace and stats" but that rust link seems to have clues.

It sure is pleasing to see perfetto handles long durations well - we work in hours and days not ns and us...

I don't suppose there is some supported way to inject macros or "ui automation" [1] into the iframe?

This is exactly what https://github.com/google/perfetto/issues/1342 is about :) It's not the highest priority issue but it is something I want to implement sooner than later.

Oh and separately you're right we should add support for also passing macros over the postMessage API. Will file a bug for this.
