Any post/tool that mentions "cross-browser debugging protocols" has my immediate +1.

Doing so from outside the browser (which gets me that much closer to staying in my IDE) has my immediate +100.

I understand the fancy side of debugging tools is still being actively evolved (interacting with/highlighting DOM elements), but surely we're to the point where a basic JS debugger protocol (break point, skip, go in, go out, etc., ...with source maps...) is doable.
