'DockAdjust' Lets You Change The Height of Your Application Dock
If you have ever wanted to adjust the height of your dock, whether to match your theme or to compliment another jailbreak tweak, then you may want to check out a new free jailbreak tweak called DockAdjust
by iOS developer GreenyDev.
This tweak allows you to adjust the height of your application dock in iOS 7, as shown above. The tweak adds a preferences pane to the Settings application where you can choose the height in pixels and then respring once you're happy with the slider's setting:
This tweak works best when you hide the application labels with another tweak, otherwise it looks goofy. You can also use a creative combination of this tweak with Springtomize or Shrink to make the application icons smaller so that your smaller dock doesn't look goofy with the large application icons. Without another tweak to compliment it, it doesn't really do the SpringBoard any justice, so we have to recommend some kind of complimentary tweak.
If you want to try it out, DockAdjust is available for free right now in Cydia's BigBoss repository. iOS 7 is required.
