The jailbreak community has always been striving to improve the way iOS handles system settings. iOS 5 failed to introduce a quicker way of managing preferences like screen brightness and Bluetooth, and jailbreakers still use tweaks like SBSettings to toggle prefs without popping into the Settings app.
More elegant solutions for enhancing iOS have started coming out in Cydia over the last year or so, and a jailbreak tweak called Swipebright brings very useful functionality to the status bar.
