Powertools for Distributed System Designers

Dmitriy Vayasura released an add-in with a whole bunch of Class Designer/Distributed System Designer power tools last year on GotDotNet: http://www.gotdotnet.com/workspaces/workspace.aspx?id=fe72608b-2b28-4cc1-9866-ea6f805f45f3

I'm wondering if anyone is specifically using the Distributed System Designer part of the power tools. If so, I would really appreciate it if you could add a comment or email me about the features you are using, what you like, and what you would like to see as a part of the product.
