A new layout aimed at users managing several accounts provides manager-level insights that are faster to identify. You get to monitor via four tiles - Performance, Accounts, Top Changes, and Accounts and Devices:
Via the Performance tile, you can easily identify and manipulate how different metrics gets displayed in the form of a line graph. It's also possible to see which changes are occurring for each account, and which metrics apply as per each device.
