iOS 4 brought with it the ability to put apps and bookmarks into folders. Unfortunately, the implementation is quite limited.
FolderEnhancer takes this feature and improves upon it, making it a viable solution for organizing and accessing your apps.
Features
Open folders faster.
Create multiple pages of icons inside of folders.
Create folders inside of folders.
Create folders directly on the dock.
Supports Iconoclasm for custom layouts inside of folders.
Extends MultiIconMover to allow moving multiple icons into/out of folders.
Options include hiding the folder name and wallpaper, as well as disabling animations.
Changes
NEW: "Reset to Defaults" button added to Settings panel.
FIX: Improved rotation on iPad; folders now actually rotate instead of closing and reopening.
Bookmarks
