Currently each control shows the failed, successful, and waived test results. You can view the Scan Results from the button to the right, but you can not filter.
For example... If I have 1000 nodes control-x is running against and only one fails, I have to scroll through all 1000 nodes to find the pink exclamation point or download a CSV report and filter it using Excel. It would be nice to be able to filter right in the web interface so we don't have to download reports all the time and not have scroll through all 1000 nodes to find the one failed node.
