The ability to click on one of the pie chart slices and have that collection of devices pop up/out for evaluation/further analysis.
When I click the chart all I get is an empty report, please fix. All me reporting services are up and work, clicking any other chart in the Office 365 Client Management "portal" show populated reports.

Also to click on the slices of the Office 365 Client Channels chart and have a view of the devices in each channel.
