I'm honestly trying hard to think of a Windows application I use where I engage with application specific non-modal dialogs. Large or otherwise. I'm sure others probably have examples of ones that they use all the time (that's why I won't stand in the way here). And for it to minimize outside of the main window of the application it's a part of feels and looks strange to me. I think I was expecting more of an MDI interface when it was being discussed. It's probably just me. And if I keep on using things the way I always have, this shouldn't really affect me anyway.
