I would love that too. Blows my mind sometimes how much CPU some pages or sites use. One of my kids plays Moshi Monsters, and that seems to challenge the CPU more than even Far cry 3. Which to me is absurd. I suppose that would be something to do with MM not using the GPU?

So yeah, a CPU indicator in the tab could be handy.

Moshi Monsters must use some very realistic monster fur rendering if it's heavier than Far cry 3 ;)

Dunno mate. But I do wish I could hunt and skin the little buggers, like in FC3!!!

You can already do that. Use the Chrome Task Manager. http://googlechrometutorial.com/google-chrome-other-settings...

I use that but it'd be great to see at a glance which tab is misbehaving

That would actually be a very good thing to have.
