Make the Scroll Bar Indicator Thinner With 'ScrollThindicator'
The scroll bar indicator appears just about anywhere in iOS that you can scroll and its length depends on how much scrolling can be done in the interface. Usually application views with a lot of scrolling, such as Mobile Safari, have a really short scroll bar indicator. On the contrary, certain preferences panes in the Settings application may have less to scroll through and this creates a taller scroll bar indicator. These size changes are dynamic and are intended to help the user perceive how much content is capable of being scrolled through on the page they are viewing.
While the height of the scroll bar indicator can change, the width does not. A new jailbreak tweak dubbed ScrollThindicator
by iOS developer r_plus
allows the user to have a thinner scroll bar indicator. The difference in thickness is indicated by the above screenshots. As you can see, the thinner scrolling bar is ultimately getting the same job done, but is using less space in doing so.
The change is one-hundred percent aesthetic and has no true benefits except maybe for having a scroll bar indicator that is less obtrusive on Web content such as pictures, since it uses less of the display’s pixels. For most of iOS’ applications, the scroll bar indicator is so far to the right that it never gets the chance to overlap anything on the screen.
One major issue with the tweak is for people where eyesight is a problem, the thinner scroll bar indicator may actually be harder to see, if not impossible to see.
Apart from the size, the scroll bar indicator retains its original transparent appearance and color. ScrollThindicator does not come with any options to configure, so the only way to disable it is to uninstall the tweak. For anyone that is interested, the tweak is open source and the source code for it can be viewed on Github
