Agreed. Easy creation and management of additional contextual identities, even ephemeral ones that exist only for that particular browser session, would be terrific. In addition, I'd like the ability to fine tune which items are isolated versus shared. I think in many cases, but not all, I'd like to shift saved passwords and form data into the identity contexts and away from the shared context. Not having to manually manage credentials when using multiple distinct sessions of a single web service would be nice.
