If you own an iDevice running iOS 5, and it is jail broken, then you must have downloaded many jailbreak widgets and apps not only to enhance the capabilities of your device but specifically to add more utilities to iOS 5 Notification Center. If you are still looking for newer jailbreak widgets for the Notification Center, you can check out the latest one known as WeeKillBackground Pro. It is an app that makes the things easier by allowing you to close the multiple apps running on your device right from the Notification Center.
It is a simple widget which does not add any extra icon to the springboard, nor provides with the additional features rather it just makes the already existing functionality much simpler than before. All that it does that it let the users close all the running apps directly via a single option from the Notification Center.
The app adds plenty of options to the Settings and let you customize many things with this app in your own way. You can select and set the custom images, dismiss options, text and one as the best option to exclude the apps which you do not want to close while you kill all the running apps.
If you think WeeKillBackground Pro app useful for you, just go to the Cydia App Store where the app is available under the BigBoss repo costing you only $0.99.
