When viewing your storefront, you will see a "Rating" field under each design. If you want to move one design ahead of another design, just make sure that the rating of the design you want to show up earlier is a higher number than the design that you want to come after. When you're satisfied with all of your ratings, click the "Update Your Store" button.
We recommend leaving a large, numerical gap between your designs. For example, give your first-place design a 90000 rating. Give your second-place design a 80000 rating. Then, let's say in a few weeks, you want to move a different design to second-place, simply give it 85000 points. This strategy allows you the ability to fit any design into any slot at any time!
Note: The rating field allows for up to five digits, so the max point total is 99999.
