Sproutcore 2.0 questions

I'm trying to write a complicated app in SC2. There's no editing component yet, just a display of (lots of data). Starting from the Todos & Handlebars guides, here's some of the stuff I've had to google for, or wasn't readily obvious.

Note: I like coffeescript and haml

• Why is there sometimes references to SC.ArrayController?

  • Colin C: it was gone but its back now. we need to generate the docs again.

• Why is App.fooController an SC.Object, and App.foosController an SC.ArrayProxy? Shouldn't there just be a generic SC.Controller, or SC.CollectionController, if the behavior is different?
