Haikufull is a fullscreen app launcher, written in yab for Haiku. It only launches apps in the Applications menu, NOT those in Demos, Desktop applets or Preferences. The app was inspired by the old BeOS program BeFull, by Kevin Field. HaikuFull does not display entries in submenus, such as those for LibreOffice, Calligra or yab. You can flatten the menu, linking those entries to the ~/config/non-packaged hierarchy. A utility and menu entry are provided to do this for you. There is a Deskbar entry in Desktop applets, just to get you started. But this program should ideally be tied to a key in Shortcuts. It can also install itself as a Deskbar replicant. A launcher should launch the program and get out of the way. This is why the settings work the same way. Just hit the hotkey again and your new settings will be activated.
