Due to health issues and scheduling, I haven't had as much time as I hoped to devote to my public shop since setting up, with only a fraction of the designs available uploaded.

Have to agree with the majority of opinion above that extreme changes that demand immediate attention in order absolutely need an "opt in" or "tryout opt in" feature, allowing control to the shop owner. I now have to take time to create a logo that will fit on a smart phone - great idea, bad timing.
