Lifehacker has updated a cool little utility Adam Pash has developed, called Swept Away.

Swept Away monitors your open windows, and whenever a window hasn’t been used for a user-defined number of seconds (default 300 = 5 minutes), it automatically minimizes the window. This not only helps you keep an uncluttered view of your desktop, but in some cases the minimized program actually uses less memory (think Firefox with the trim on minimize tweak).

The new version adds a user-defined monitoring interval (default 300 milliseconds), and some bug fixes.
