App Tamer 1.2

App Tamer tames applications that are chewing up excessive CPU time and battery life on your Mac. Its unique "AutoStop" feature will stop an application when you switch away from it, and then automatically restart it when you click back to it. App Tamer includes an attractive and clear user interface for managing your running applications. It shows the average percentage of your processor(s) being used by each app, and graphically displays a history of CPU usage. You can easily enable AutoStop for any application, as well as change its processing priority in OS X.

REQUIREMENTS
Mac OS X 10.5 or later.

Version 1.2:
App Tamer's menubar icon now displays CPU usage in a number of ways. The needle on the icon moves to reflect processor load, the icon can be colorized so it turns yellow and then red as usage increases, and you can also display the CPU usage numerically next to the icon.
Problems have been fixed so that App Tamer correctly sees all processes launching and quitting. In version 1.1.2, it would occasionally lose track of an application or show an application twice.
If App Tamer's icon is not in the Dock, double-clicking on App Tamer when it's already running will open its window.
