Wish: History icon next to objects with History in the viewport

I believe that having a tiny icon (a pyramid) to indicate that an object in the viewport is History-dependent would be helpful to some Rhino users. To avoid a massive amount of such icons in the viewport, those could be set to show only for objects of a certain type (only curves, only surfaces and polysurfaces, etc) or size (only objects larger than user-set size).

An alternative is to enable rendering of the History-enabled objects in a different Hostory-specific colour, material, isocurve thickness or glowing outline.

Of course, this should be totally optional and easy to turn on and off.
