It would be nice to have a "View Stack Snapshot" or "View Stack Trace" button for each thread when doing thread monitoring. Or even a separate tab with the stack trace for each thread, updated by auto-refresh. I recently had five threads that were running, and eating 100% of CPU, even though they should have been idle, and I was able to identify those threads after activating threads monitoring. I was doing memory liveness profiling at the time, the running threads that should have been idle were the main thread, the OS - JVM signal dispatcher, and 3 user threads. However, I didn't have any idea what those threads were doing (there were probably stuck in some kind of infinite loop), and I really missed a "view stack trace" option.
Agree, this would be a useful addition to the Threads view.

A thread dump can be taken at any time during a profiling session.
