If you have too many applications crowding all the space in Unity launcher, you might be thinking of a better way to manage them. Making icons tinier by reducing the icon size is one way, but would it not be better if you could group a bunch of icons? This is what we already do in Android and iPhones. Group the apps together and save the screen space.
LauncherFolders is one such application for Ubuntu Unity that allows you to group apps, files, folders, chrome web apps, links and shell scripts in folders. And these folders then can be used directly in Unity launcher. Reminds of another similar tool Drawer, isn’t it?
