@MateoV - if you're not using the functionality in render() I would kill it. I'd keep using render() even if you pass through as it's useful to distinguish between accessing attributes of a model and accessing them for display on the screen. Programming like this makes it very easy to filter out potentially malicious strings later.

@MateoV - tracking the main view is not actually necessary. You don't wind up using this.app at all. I would keep the App view object anonymous and actually create it in boot.js. Having the router create the main view was a move of convenience in the wb-knowledge project that actually wasn't that clean...

@MateoV - It's awkward to pass on the view's collection like this. This line makes me think that we should invert the relationship between Filter and Sites view or possibly better, eliminate the Filter view. Happy to discuss this more.
