dgozman@ is the DevTools dev we have been working with. I know combining all OOPIFs in the same DevTools window is planned to be done, but not sure when in time it will happen. I'll let dgozman@ comment on that.

We are going to work on this as OOPIF progress forward. There is no specific milestone we plan for, but if you have any time concerns please tell.

alph@ can try restoring the option where timeline shows information for all processes.

I'm hoping (optimistically probably) that we can ship TDI in Q1, so I'd like to see this fixed in Q4 if at all possible. Does that work?

Looks like this work is now being tracked in  issue 652783 .
