It would be great to have such controls as webparts/widgets to place in a dashboard where we could move them around the screen to reorder how data is presented with option to save/retrieve the layout from a persistent source. In the dashboard the functionality would be to define a layout where we could add/remove, change position the widgets (like in dropthings or pageflakes). The widgets would contain controls like Kendo Grid or DataViz controls to display information. That would be a killer feature.
