btcw is great
if have a few windows open it sometimes slows the computer down if i'm doing something else, so i usually close those windows or send them to about:blank. restoring them later in reverse, it's a few clicks
but would be cool if the graphs had a "pause" button on them, and cooler still if there was an option for a timeout, say, if you didn't move the mouse over the page in 5 minutes (or timeout duration is configurable) it would automatically go to pause mode.
probably would save you some bandwidth as well, all those zombies with their operators afk shutting down
