QaLL terminates running applications. And also can relaunch every apps which are terminated by QaLL with 1 button. Of course you can specify apps you don't want to terminate.
Mac OS X is able to run many apps in parallel, but sometimes, especially when you play game or run big application, processing speed can be slow down because of other apps. So you should use QaLL to clean up needless process and feel comfortable to run big app.
