It would be nice to have ShapeSheet functions (or even menus/toolbars) that positioned shapes the way Visual Studios "Anchor" and "Dock" properties work.
What's nice about Anchor is that you can anchor to multiple sides, so that, eg. a shape will stretch with its parent, but maintain constant-offsets to sides. This is one of the essences of SmartShape behavior, but it still needs to be implemented via elemental ShapeSheet formulas.
Also functionality similar to WPF's (Windows Presentation Foundation) various stack and flow panels, which automatically arrange their children in useful ways. (I know, wink, wink...)
how true ...
