Hi Nathan, here are 3 great suggestions from another topic found here:
"Sadly 2.82 doesn’t improve the situation much.
-
you still can’t select multiple hierarchies
-
you still can’t select a hierarchy of hidden parent objects (IMHO visibility should not effect selection behaviour in the Outliner)
-
List item
you still can’t move a selected hierarchy from one collection to another without creating duplicate references.
Generally speaking, as soon as you try to restructure a scene graph with empty-hierarchy into a collection structure, you are screwed. I really hope that the team keeps up the great work and will give the Outline the love it requires."
