Some operations only apply to the child elements if you navigate through the entire parent-child-subchild-etc. hierarchies to manually select every nested item and this can be a huge pain if you try to organize objects and other elements logically by nesting them. Delete is an obvious example, and I think hiding is as well. I think there was some other operation I ran into this issue with too, but I can’t recall off hand what it was. I know going to the outliner and selecting “Delete Hierarchy” works, but it would be preferable if that were the default behavior, or at least works with a keystroke.
I modeled a medieval house that was somewhat complex and it became a huge headache. Is there a way to make it less of one?
