See the objects and the links between them! There are three tools: 1) 'SRE collaboration' lets you build a diagram of objects with links. 2) 'SRE Object Browser' gives flattened description of an object with its identity, state and behavior, the last two are editable. 3) 'ObjecttraceRM:levels:' dumps the stack to the Transcript.
