“The Informer is a great widget that will
display vital statistics about your
computer like CPU and memory usage,
check your mail, give you quick
access to apps and folders
without cluttering up your
desktop, and even play
Internet radio stations.”



This Widget monitors your system resources (CPU usage, disk usage, memory usage, swap usage, system uptime, WiFi, battery life, Recycle Bin/Trash), Internet resources (RSS feeds, IMAP4/POP3 MailBoxes and Gmail Inbox), etc., and displays it on your desktop.

You can set up multiple sensors (useful for multiple Gmail accounts or RSS feeds) too!
