iSlayer today announced the release of iStat pro 3, the latest release of its chart topping system monitoring widget. New features of version 3 include: four new and completely different skin designs that make better use of screen space; fully anti-aliased CPU and memory graphs, drawn by the iStat Cocoa plug-in; a new ‘Processes’ section that lists the top five tasks; the ability to control which drives, network interfaces, temp sensors and fan sensors are shown or hidden; and a new icon to match the new skins.
