The 'Manage applications' button works the same as before. The only differences are that it's now a push button, and the dark theme is used for the application manager. Some screenshots of the folder creation process: Applications are added to folder using drag/drop. You can remove an application from a folder by first opening the folder, then dragging the application outside of the folder. The icon will then reappear in the main application list. The only limitation is that applications can only be added to a single folder. I suppose you could overcome this by creating a duplicate desktop file with a different filename.
