Was thinking of including storage I/O profiling too, so e.g. via hre.tracer.storageProfile(true) (argument true resets collection to zero).

I agree with your comment on the other issue, it already prints a fair amount, and it would probably have to take into account multiple contracts so output could get complicated / verbose fairly quickly, but this kind of thing is super useful and I can't find it as easy to use in any other tool.

I will have a look into how to get the line numbers etc. and see if I can get around to adding some notes or hacking on some code.
