Free system monitoring Dashboard widget iStat Pro has been updated, adding new features.

The developers at iSlayer first shipped a version of the widget 14 momths ago. Today it offers a visual read out of all the information a user would expect to access using Mac OS X's Activity Viewer.

iSlayer has made its widget smaller and more efficient than before. The new release also benefits from four different skin designs, fully anti-aliased CPU and memory usage graphs, a new Process viewer, a new icon and the ability to control which drives, network interfaces, temperature and/or fan sensors are shown or hidden.

You can download a copy of the widget, and find further information about it here.
