Here is a short video going through some of the new features. I want to apologize in advance for the poor frame rate of the video, since it was taken from my laptop and somehow the video grabber couldn't manage a higher rate. Since I can't find how to embed it in here with its original size, consider playing it fullscreen.
I hope the video encourages you to test the QML profiler and use it for your own applications. Feel free to give us any feedback about the current profiler, for example suggesting new features that would be helpful for you.
