If you are working in the Layers tab, and wish to remove a design layer that is visible, or has hidden visibility, you can:
- Open the layers tab.
- Select the layer you wish to remove by clicking on it, and press the 'Delete' (trash can) button at the top right of the Actionbar. Alternatively, you can also select the layer and press 'Delete' on your keyboard.
Using the delete option is a permanent deletion. If you are unsure about keeping an item on your design, use the 'Hide' functionality in layers so you can turn the layer on, and off.
