It has been a couple of months since we shipped Visual Studio 2005 Beta1. A lot of customers have started looking into Class Designer. The initial response has been great. We have also been getting great feedback on features that customers would like to see in the product through the logging of bugs/suggestions at the MSDN Feedback Center. Thanks to all that have participated so far. Comments have ranged from "we need something similar to the UML Sequence Diagrams" to "I would like to see member details on the shapes in the class diagram."
Logging these issues helps us to understand and track them. More importantly, it gives customers a voice to 'vote' for their favorite feature. While we can't promise all these suggestions will make it into the product this release, adding votes to your favorite feature will certainly increase the likelihood the important ones will. Suggestions that don’t make it into this release will be tracked and considered for future releases.
Here is a link to a customer's blog on the class designer features he would like to see in the product.
