Wix Logo Request: Saving Merchandise Designs in the Print Shop

Collecting votes
Currently, it is not possible to save merchandise designs (business cards, stickers, mugs etc.) you've worked on in the Print Shop, and edit them later. 
Workaround:
You can save your merchandise design by adding it to your cart in the Print Shop. When you come back to your cart later, you can click Edit Item next to the relevant design and continue customizing it.
We are always working to update and improve our products, and your feedback is greatly appreciated.
