Feature request: Device groups drop down

Hi, 

I was wondering if it would be possible to show the number of up/down devices in the device groups dropdown, rather than the number of devices total? 

Just like on the 'All Devices' button, but for each group.

That way we can see very quickly if there is an issue on a certain network. 

I've attached a screenshot of the dropdown that I mean from the demo, but on our version we have multiple groups. 

Ta,

Jenny
