Created attachment 290027 [details] WIP This is a very early stage WIP. All method names are likely to change. I'm trying to gauge how useful a heatmap visualization is (say, as opposed to "perf gutter" in Chrome DevTools). How to see the heatmap: 1. Record a Timeline. 2. Open a JS resource (that has function calls captured in the timeline recording). Once timeline is recorded, there's currently no way to hide the heatmap. I'll add a button before to the resource toolbar (before the [T] icon) to hide the heatmap.
