This is a amazing way to visualize one of the most complex dumps! Kudos to team

There should be a way to compare thread dumps that are captured over time. That is what tells the real problem. Right now we can load multiple dumps but have to manually check through them to see if same thread appears multiple times.

Awesome!! No need to install any software and interpret the results. The results were crisp and clear.
