Ability to tame differently on startup, perhaps for the 1st 30 minutes or so.
Able to drastically tame some apps (even suspend) based on number of times exceeding a threshold CPU/memory/etc.
Different rules for battery power versus plugged in.
Able to manually invoke the "battery power" taming mode (for overnight updates, or when I want computer to stay cool.) Actually, a better approach might be to allow forcing the CPU to downshift to a lower speed. Many laptops have this built in, based on power settings, etc.
able to collect and graph statistics on specific programs over time (days or weeks perhaps). Also, able to collect info on ALL programs for specified time interval (minutes, hours...)
