OOps hierarchies

Some time ago I proposed a schematic view. It's the most useful tool to know how a hierarchy, or even a scene, is organized. How parented and constrained are the elements with eachothers . And it's a live changer for rigging (actually it's really hard to find what element masters one another in a complicated rig).

Someone told me about "Oops view" from years ago... after some research I found that that was, more or less, the feature I'm proposing...

So now I propose to bring back "Oops view" again to Blender :) even if it's only for pure visualization (without any selectivity or interaction with represented elements) it is a huge improvement.
