Yes, we intend to add sorting to this. There's probably some confusion on how these are sorted and the labeling - it should be the last time anything related to the post (comments or answers) are added/updated that makes the posting pop to the top. The date displayed there may be associated with the original posting, not the related children. I'll verify.

We did have another request to display the number of comments and answers in two additional columns. Would this be helpful or valuable to have here?

Thanks for the posting. I haven't put up the release notes yet, but the "view by member" is one step of several features we'll be adding in this area. You can now find members and see their content under the Connect | Members menu but we'll be adding some other mechanism for doing the same from wherever you see a user's name. Upcoming builds will also have "following" by person and by tag.

We recognize there's a need for a class reference, so don't worry, it's not going away. The question is about functionality and completeness of the current class reference utility so there may be some refactoring in addition to changing the UI skin. There's some internal discussion about how it works and the way the information there is obtained. They'll be more on this in the next few weeks.
