FolderEnhancer is one of my favorite Cydia tweaks for the iPhone which brings several additional functionalities to Apple’s implementation of folders in iOS 4.x. It makes opening folders faster, full-screen (above the dock) and allows for infinite apps inside each folders. You can also enable scrolling and pagination.
FolderEnhancer was updated to support the iPad a few days ago, but it’s not quite ready yet. Most of all, the tweak won’t let you put more than 22 apps in a folder (otherwise, the iPad will crash) and the landscape view isn’t ready. Pagination and scrolling haven’t been updated for the tablet, either. Still, the tweak in portrait mode makes opening folders a breeze, and I like the larger view that it offers. I usually put a lot of apps in a folder, so having a bigger view for “just a few icons” is not a problem to me.
FolderEnhancer for iPhone and iPad is available at $2.49 in the Cydia Store.
