How to delete Groups of Layers

If you wish to delete a group of layers:

1. Open the layers tab.
2. Click on a group to select it.
3. Click the 'Delete' button in the Actionbar, or press the 'Delete' key on your keyboard.

Note that deleting a group is permanent! If you're not 100% sure you won't require the elements, you can always use the 'hide' group option.
