Hi Tudor,
Thank you for the suggestion, I want to visualize one of my projects. I tried to use RTDominanceTreeLayout from Moose with "Compression" package in Moose Panel, and found it is used in "All famixnamespaces" and "All famixpackages" (this one is giving a MessageNotUnderstood: FAMIXClass>>FAMIXPackage). I always get 2 namespaces so I couldn't check how close enough is RTDominanceTreeLayout from Moose.
However, I checked the mailing list and found a script using RTDominanceTreeLayout so I would start from there.
