In a day and age where the iPhone is becoming more gesture-based, it peeves me that the Cydia app on jailbroken handsets hasn’t adopted more gesture-driven controls.
Perhaps one of the most obvious gesture controls that Cydia could benefit from is Pull to Refresh in the Changes tab – this would replace having to manually tap on the Refresh button at the top-left of the app just to see if there are any new jailbreak tweaks or extensions worth installing.
