- Move visible launchers to the available list (thus hiding them from the launchbar) by dragging them
- You can reorder the items in the lists by dragging
- You can create new launchers by right-clicking on the "Visible launchers" folder
- If you want to get back to the default setup, you can find "reset" in the context menu.
