I admittedly haven't taken an in-depth look over the framework, but what specifically did you feel was missing from Backbone? Anything we can improve?

I don't find this list [0] to be particularly helpful. It looks like the main addition is filtered collections and relations, which there are many ways of doing [1] or pretty easily added via a plugin.

(And as an aside, Backbone absolutely does support IE6, and goes out of its way to maintain bc, particularly in History).
