A big complaint I've had about Android for some time now regards adding items to the home screen. The basic way of doing things is you scroll through a text list, pick something from that list and plop it onto whatever home screen you're currently on. That requires your brain to remember what's already on the home screen, and to know what the new item actually looks like. If it's an icon, that's easy enough. If it's a widget, well, you get what size it is (1x1, 2x2, etc.), but that's it.
Samsung's done us a solid in the latest version of Touchwiz, as seen on the Galaxy S II Epic 4G Touch. It's basically taken the Honeycomb way of doing things and scalled it down for the smaller screen. You can see the full home screen (and even flip though them) as well as see the widget or shortcut you're looking to add.
It's a small but ingenious change. Kudos, Samsung.
