One of the common modifications a lot of people like to do with a jailbroken iPhone is to change the look and feel of the dock. A person can remove or change the background blur, increase the amount of icons or even completely get rid it. Vinculum, by developer William Vabrinskas, adds a whole new dimension of functionality to the dock by tucking an Android-like app drawer neatly underneath it just a quick swipe away.
Within Vinculum there are a lot of options including hiding the grabber, changing the size of icons, and using a dark background which also changes your dock background. You can also set it to automatically activate search after swiping up, this makes it just like Spotlight and could replace it for some users. As with most jailbreak tweaks, users can customize the experience to suit their needs.
Vinculum was created to fulfill a request on Reddit and was initially going to be known by a different name, but was rejected due to possible copyright infringement.
