Cool, thanks for sharing. Been using the grouping and pinning feature in chrome for a bit then saving the groups i care about to try to emulate this behavior, but still a long way off from ideal; the one dimension of tabs at the top level means the UI gets crowded quickly. Had the tree-style tabs extension for a bit but didn't love its interface and found it to be more trouble than it was worth.
