If you want to delete a text/artwork layer, there are 3 ways to do so:
- Select the layer by long pressing or selecting it from the layer menu, then press the “x” button on the top right of the layer.
- Swipe the layer in the side menu to the left, and select "delete."
- Drag the layer outside of the main edit area. You can turn this on/off in the preferences panel.
If you want to delete a drawing layer, swipe it left in the Layer Menu and select "delete."
