Feature Request: Add an ability to ignore some threads

When I'm debugging weblogic server or tibco jms applications, I often found
there are a bunch of threads which contains no useful information for me
at all... ie idle thread. It would be nice if I can ignore those threads.

i.e.

ExecuteThread
wait() -1 java.lang.Object
wait() 429 java.lang.Object
waitForRequest() 153 weblogic.kernel.ExecuteThread
run() 172 weblogic.kernel.ExecuteThread

or

E4JMS Session Dispatcher
wait() -1 java.lang.Object
wait() 429 java.lang.Object
_getAsyncMessage() 1348 com.tibco.tibjms.TibjmsSession
_dispatchAsyncMessage() 1379 com.tibco.tibjms.TibjmsSession
run() 2506 com.tibco.TibjmsSession$Dispatcher
