Sometimes applications crashes, freeze or otherwise develop an appetite for every last byte of system resources. It doesn't happen often, but it does happen. When an application 'crashes' it usually doesn't require any input from you (other than banging your head against the wall at any unsaved work now lost). But applications that decide to 'hang' or 'freeze' not only get in the way of you carrying on with whatever you were doing but can often max out your system resources - leaving you with no option but to reboot or nose-dive into the command line. That's where FlashFreeze by Sergey 'shnatsel' Davidoff is of use.
Long-time users of Ubuntu might recall that a handy 'Force Quit' applet was once available to add to the desktop panel, which made 'closing' misbehaving applications a cinch. Thankfully for the lazy amongst us reader Josh Leverette has put together a script that adds a 'Force Close' button to the Unity Launcher. With one click you can once again kill crashy, CPU-hogging applications without having to reboot or revert to the Terminal.
Crashy apps hanging around chomping on your resources? Kill it quickly with the newly formed 'Indicator-Forceclose'.
