Hi Chilesju,
Looks like Yevgeniya has already passed along your feature request for more group views, so hopefully development can work that into a release soon. Because we do have a wide variety of customers, each having their unique requirements in what types of views they have, it's pretty hard to have an exhaustive list of views that covers everyone.
I can give you a sneak peek, though, and let you know that Development is working on a method whereby users can define their own views. I can't say too much, lest I incur the wrath of the Development Team, but I have heard they intend to roll something like that out in the first half of 2009.
One way or another we'll hopefully get something into the software that will allow you to see the data the way you're wishing to see it. Thanks again for the feature request.
Best wishes,
Eric
