One of many small things that would be useful in Unreal.
Large projects have world outliner with objects in folders and frequently folders in folder. Accidently click the wrong thing in the viewport and you’re now deep in the middle of a folder.
Rather than having twirl things closed (or open) consider alt key like other apps that applies the action to everything in the folder. So a single click causes the expanded folders to revert to all closed or all the way open.
