'TinyGrid+' Lets You Customize the Icon Grid in Folder Icons on the iOS Home Screen
For a little extra customization over the folder icons on your Home Screen, check out a new jailbreak tweak called TinyGrid+
by iOS developer magn2o.
This tweak will let you change up the stock 3x3 icon grid inside of the folder icons on your Home Screen to different grid patterns so that you can make it look better depending on your tastes. The tweak will add a preferences pane to your Settings application where you can configure your folder icons to your liking:
Here, you can enable or disable the tweak on demand, and choose a custom grid of your choice. You can customize both the columns and rows individually, and you can have any number between 1-5 for either. You'll also find sliders for adjusting the transparency level of the folder icon, the size of the application icons in the grid, and the spacing between the application icons in the grid. At the bottom, you'll find two buttons – one is used to saving your changes and respringing, and the other is used for resetting the settings to the defaults and respringing.
Depending on your grid settings, you'll want to adjust your application icon sizes in the grid to make them align properly to look good. You may need to respring a few times, as there's no real preview option available.
If you want to give TinyGrid+ a try, it's available for 99¢*in Cydia's BigBoss repository.
