Cydia has endured a lot of criticism over the years from the jailbreak community because of its seemingly out-of-style user interface and lack of modern aesthetics. Such criticisms have given rise to third-party alternatives, such as Sileo.
But in case you forgot, Cydia as a platform is entirely customizable ever since Jay Freeman updated the Cydia Substrate framework to allow for Cydia-centric jailbreak tweaks. With that in mind, iOS developer iOSNJB took to the drawing board to produce a new release called CydiaXIStyle 2.0.
