Hi Mike,

1. Not as far as I know.
2. JMC-5684 is more about visualizing the native method sample
(jdk.NativeMethodSample) event than showing native frames / mixed native &
Java stacktraces.
3. For showing other stuff in the Flame Chart, just click on something
representing some events. For example, got to the event browser and select
the native method sample events - now you have a flame graph of them.

Kind regards,
Marcus
