Borma is right. Launch Pad looks pretty, but it's far too much trouble to organize, even using this clever folder technique. I organize my iPhone screens, because that's the only option I have. But OS X offers much better options, in my case folders and subfolders in the Dock, organizing Launch Pad isn't worth the trouble.

The key problem is that Apple's UI staff now think we're too stupid to use folders and increasingly the only way they're offering us to find things is either a clumsy search mechanism or a pain-to-set-up Launch Pad. Better design would have perhaps a dozen well-defined subfolders inside the Applications folder, with developers required to specify which one their app is assigned. That'd end the current glut of apps in the root Application folder. Those same subfolders could then named pages in Launch Pad with no labor by users.
