Dashboard filter using output

I agree, I would say that at the very least every column should be able to be sorted in an ascending or descending order. To be fair, you cant sort / filter on the classic device table dashboard,, but you can build a top N widget to display what your looking for.

To follow the same pattern as the Classic Dashboards I was able to create a second widget adjacent to the device table and build a leaderboard bar chart showing just CPU info that shows the name of the device and the CPU consumption. I think you can get where your trying to go, but in a different way than you were thinking.
