Here at Celestial we have been particularly eager to get our hands on the new UI system. We very pleased with it even though we don't feel it completely meets our requirements just yet. In particular we want a better way to manage the look and feel and the layout. Also we miss the easy way the old GUI would allow us to build UI from code. With that in mind we have started building an extension we are calling Snap UI.
