Great stuff. Opening generated files with long lines in emacs has been hurting me pretty badly, lately. Thanks!
I made a tracing tool for Emacs which outputs Chromium traces, which I find much more useful than the profiler for interactive latency things. If this sounds helpful to other people it’s available here: https://gist.github.com/trishume/40bf7045a23412d4c016f5e8533437db
Is there a reason the font weight is so low? The text is already grey, making it light doesn’t help with readability.
Presumably because that weight looks really nice on macOS, which dilates fonts. It looks strange with ClearType or FreeType.
