Because iOS4 multitasking sucks... Tired of having to return to SpringBoard, double-tap the home button, tap and hold, then press the small quit button to quit an app? Tired of removing closed apps manually from the multitasking bar? With MultiCleaner you can quit apps with just an Activator shortcut and customize the multitasking bar however you like.

“Quit all apps” exceptions
faster and better way to quit all apps (hopefully)
new option to inhibit wriggling in edit mode
new option to move closed apps to the back of the bar
