I have been evaluating this new features and I think it's really useful. What would make it even more useful is if it could detect and show second level dependencies.
For example "myproject" has two project dependencies, projectA and projectB, projectB is directly referenced by projectA. If my code only uses classes from projectA, projetctB will be shown as "Unused". What I would like to see is whether projectB is used by any of the projects/assemblies directly referenced in myproject as I want to keep my reference to projectB.
