I'm also still wrapping my head around the presentation, but I agree- Presenter objects are separate from the Widget hierarchy - the just connect via the Widgets/interfaces exposed in the Display interface. I think the way to have Presenter objects clean up after themselves would be to have a Presenter superclass that registers itself with the event bus to listen for 'Window Closing' events, and cleans itself up. The main app would have an event listener for 'document.onUnload' events that notifies the event bus and any Presenters can then tidy up. I'd love to see some code for the PlaceManager though...
