The idea is to have multiple presenters throwing views up into their own little piece of real estate on the screen, then depending on different events, swap out presenters. For instance I want user information in one little box on the screen, and a header across the top. I want the user information screen to disappear and show a modify user screen in it's place when they click the modify user button, but I don't want anything to happen to the header when that happens. I have a different presenter for each piece of the application, for instance the User Screen, a Header, a part that shows a list of items. I already tried to do this, but when an event happened, a new screen would show and wipe out another one. In my case the modify user button was clicked, and it wiped out the header.
I don't know how passing multiple containers to a presenter would solve this problem unless it was just a reference to a structure that was housing all of them. For instance a whole DockPanel gets passed down to each presenter and they all add themselves to the dock panel. I might try that and see what happens, but if anyone else has a better idea please let me know!
