When Apple released iOS 11 last year, one of the first things I noticed and didn’t particularly adore were those unnecessarily-large titles that show up at the tops of various stock apps.
Assuming your iOS 11 device has been jailbroken with Electra, you can now install a new free jailbreak tweak called NoLargeTitles by iOS developer CoolStar to do away with these unsightly titles and revert to how things looked in iOS 10 and earlier.
