Is there a way to isolate a selection in the editor and all non selected items to be hidden in the 3D view? Similar to blender's isolate selection. My 3D scenes can get very busy and it would be nice to declutter while working on only a few elements.

I temporarily turn off the visibility of the relevant items when I'm having that problem.

I would have to uncheck visibility on hundreds of nodes in the scene tree to only see the one I want. This is not very efficient.

Can you arrange them in groups? If a node's visibility is turned off, its children also become invisible.
