One suggestion left in a comment is to default all nesting groups to closed by default, and persist that state between opening and closing the list view panel. If you then select a nested block in the canvas, the list view if open should expand that tree view, potentially even scroll to it. Are any aspects of this behavior tracked? The scrolling bit I feel has been discussed somewhere. Happy to open a new ticket if need be.

@talldan It seems most issues here are addressed. Could we close this, and maybe move any remaining important items to #63255?
