A PointerFinder or Inspector could indeed be the object holding onto something that should be garbage collected, and these UI objects can become disconnected from the scene graph, for example left in some global variable during a debugging session. But think carefully about the criteria for choosing which PointerFinders and Inspectors are considered excludable; does one include those in different projects? What about ones that are hidden or partially obscured behind other windows?

Exactly. Much better example than mine.
