Get Rid Of That Shapelayer Outline
If you've worked with a shape layer, you've probably noticed the appearance of a thin outline around the shape. The outline you see around a shape layer really doesn't mean anything. It won't print or show up on a saved Web image; however, it does look flat-out distracting when you're trying to work with your images. Just click the mask next to the shape layer it's on, and that outline will disappear. Click on it again if you ever want to turn it back on.
