I was one of those that requested a way to profile repaints. Thank you for adding the aggregate repaint view. The video showing the margin-left vs. transform repaints is exactly the kind of thing developers can take advantage of.
Question: does the aggregate repaint view indicate what caused the repaint? Determining that isn't always as easy or obvious as the margin-left vs. transform example in the video, so it'd be a huge benefit if that was included.
