Setup your Project Background
Once you have opened your project in the designer, you can set up a background for your entire screenshot set.
Add a panoramic background to create a continuous flow across all screenshots. This can be an image, a solid colour, or a gradient.
You can also set a different background for each screen inside the designer. A screen background will sit on top of your project or panoramic background.
For example, you might use an image as the project background, then add a gradient overlay to an individual screen background.
