Yes, this is nice to see.

Nice. That does probably slow down programs we are tracing even more
though. So it should probably not be on by default. You also need to
think about libraries that might be loaded/unloaded dynamically. How
would that interact with the stacktraces? It means that at a later time
the original stacktrace might not be valid, or that it might not be
possible to find the actual code back.

Another bluesky idea. Seeing the stack trace addresses I thought it
would be nice if anywhere in the gui where you have a code address you
could simple add a CodeObserver by right-clicking, or some other
mechanism to the current Task or the whole Process. That way you can
quickly start with breakpointing in the gui and don't have to do any
code/line/address conversions (yet).
