I've started playing with NSCollectionView and everything worked out beautifully (custom views, selection state handling for items etc.). One thing I can't figure out is how my application/document gets notified about a change of selection.
If you bind the collection view to an NSArrayController, you can observe the controller's selection-related properties, either programmatically or by using bindings in IB. For example, you can bind a button's "enabled" property to the controller's "canRemove", to enable the button only when there's a selection.
