Configuring the way your iOS 7 Notification Center will look and behave has never been easier. With a new free jailbreak tweak called BetterNC7
by iOS developer AppleStuffTutorials will give you all kinds of configuration options to making Notification Center easier to use, better to look at, and more.
BetterNC7 adds a preferences pane to the Settings application once installed, as shown below:
From here, you can adjust settings such as enabling or disabling the tweak on demand, hiding or showing the top and/or bottom separators, hiding or showing the Yahoo! logo, hiding or showing the "x" button, replacing the "x" button with a "clear" button, showing or hiding any of the three different tabs in Notification Center (Today, All, Missed), hide or show Notification Center content, enable or disable a transparent Notification Center, enable or disable the Notification Center blur, hide or show the Status Bar, hide or show the grabbers.
In addition, you will be able to configure how many lines of text are allowed to appear for notifications that appear in Notification Center, as well as choose the height of your notification header. You will need to use the respring button included in the preferences pane to respring the device and save your changes each time you make changes to this preferences pane.
BetterNC7 has a ton of options that are use-friendly and can give your iOS 7 Notification Center the look and feel you want. If you would like to give it a try, it's available for free right now in Cydia's BigBoss repository.
