There was simply too much information in that table to be usable. It probably still needs to lose more weight in favor of moving things to a more admin-oriented detail page. However, we need to get real user feedback on what data is critical for the overview vs. what can be in a detail page. Fixes bug 944506. Change-Id: Iaad218bc6ed6647645c5943920467bec097a0a2d
