Windows 8 Task Manager Should Include Battery Performance

I know it's a little late to get it included, since the RTM is already out, but I was just thinking that it'd be a great idea for the task manager to have a "Battery" section under performance, so we could get some actual metrics on battery usage. On Windows 7, I used to use BatteryBar all the time because it was able to show the current battery drain, the battery health, and predicted battery length based on statistical analysis of past data. On Windows 8, all we get is an icon when you open the charms bar, and an icon on the desktop that gives the same type of estimates as stock Windows 7. Including all this extra information in the Task Manager under the Performance section would be very helpful. It already contains CPU, Memory, Disk, Bluetooth, Wi-Fi, and Ethernet sections, so why not a Battery section?
