Additional instrumentation needed on "resources" tab

Description
It would be useful to see different indications for user/system/hard-interrupt/soft-irq (or maybe just user/system+soft-irq/hard-interrupt) graphing in the "CPU History" display.
Also, an additional display is needed, one for disk throughput.
I would use a single graph, but one indicator per physical disk drive (ignore partitions), and map both blocks-read and blocks-written (a la "iostat"). Or alternatively do multiple separate bar graphs, one per device.
I do a lot of builds of distros from scratch (once per commit to confirm that things aren't broken)... and it's handy to have good instrumentation of where your bottlenecks are.
Yes, you can dig down with a terminal running iostat constantly, but sometimes it's useful just to see it graphically.
