I was in the test pilot for this and I had one singular gripe which I don't think has been addressed or brought up anywhere else I've seen: I want to be able to move a tab from one container to another. It's so easy to open a tab in the default container, or the wrong container, and being able to move that tab, along with all the data it has spawned (like cookies) would make this a killer feature for me. The only other thing, which admittedly makes my one singular gripe less singular, is that I didn't see any separation in the history, as far as what was in a given container. In an ideal world, each container would have its own "Show all history" data.
