I agree, this is exciting. I just hope, if they implement terminal withing chrome, when one presses ctrl+p it will select previous command from buffer, and not print the page. I enjoy working in chrome devtools, I use it just like a shell and love it... and then I press ctrl+p and get all frustrated...
