==================== Summary ====================

Name: Kernel-pre.1430
Author: pre
Time: 1 December 2021, 2:57:51.27597 pm

Ancestors: Kernel-nice.1429

Slightly improves the ObjectViewer by returning the ObjectViewer whenever the wrapped object would return itself. Thereby, the ObjectViewer stays in place somewhat longer. 
Recategorizes the ObjectViewer interface on Object to debugging, as it does not have anything to do with dependents access.
