Widgets and Revamped Notifications Coming to iOS 5?

How about a universal file system? App developers have largely addressed this gap, but the UI and capabilities in each app can be very different and this really messes up the otherwise amazing uniformity of the UI across all functions. For example, do some file management in GoodReader and then compare to Dropbox. You'll get a headache. I'd like to see Apple tie this all together in their normal amazing fashion.
