The menu allows (supposedly) to move all objects from a category to its parent. This is seldom (if ever) used and is potentially dangerous and destructive. It is potentially confusing with the menu to view all objects with children. The menu (and associated backend code) should be removed.
The feature is actually to move the selection to a parent category of the one that is clicked on... which is very much undiscoverable. One more reason to remove this.
