From David Burton:
This is a simple, highly customisable system readout script. It handles: CPU load; Free and loaded memory; Drive size and free space; and Wifi status. Each readout can be hidden, rearranged, changed colour and changed in size either globally or individually. You can also move them all together by double clicking, double click again to disable. Other settings include transparent background, font face.
More specific functionality includes highlight cpu when load is 99% or over, alarm and battery alert when under a set value. Some can be displayed in bars instead of percentages. This version is the first release on CNET Download.com.
