associations

• transactions

• undo/redo

• commit changes

• Scopes will bindable in ember, like DS.filter. This means that "associations" are bindable, since they are scopes. You know when an item is added or removed.

• Stores should have transactions that you can commit at the end of a large operation.

• should stores only be instantiated once, storing a bunch of types? maybe not.

  • pros: batch send data from one central location.
  • cons: everything has to take a 'type'
