A component of iOS that you probably see rather frequently when you use the Settings app or other scrollable interfaces is the scrollbar that appears at the right side of the display to give you an idea of where you are on the page.
The scrollbar does a great job of being both a reference point and a means of scrolling up or down a page much more quickly, but it’s lacking something: customization. That’s where a newly released jailbreak tweak called Color My Scrolls by iOS developer TheLazyITGuy comes into play.
