I now added a simple implementation in the GTInspector to have Pointers available for all objects. Perhaps it is overdoing it to have it by default on all objects, but it was cheap to implement in a crude way. I still do not eliminate all inspector related objects that point to the current object, but it's a start (see attached the pointers to Smalltalk).
Object>>gtInspectorPointersIn: composite
<gtInspectorPresentationOrder: 20>
composite list
title: 'Pointers';
display: [ (self pointersToExcept: { self })
reject: [ :each | each pointsOnlyWeaklyTo: self ] ];
format: [ :each | GTObjectPrinter new asTruncatedTextFrom: each ];
showOnly: 50
