Right now, when one sub-object selects something like a curve segment or a polysurface face and one uses Copy>InPlace (or ExtractSrf/Copy=Yes), the subobject is still selected at the end.
Usually right after that one wants to do something with the copied object, not the original subobject. So this is painful, as you think the copy is selected but it’s not. It is actually the subobject which is still selected and that is wrong 99 times out of 100.
