Thank you for sharing!
Just tried it out. Yes, it takes the most recently listed items, I just rearranged the shop yesterday but it doesnt help. Would be better it it took featured items!
Well, it may be not too bad - showing the latest items, like a trend of the week/month/ season, who knows?
Anyway, its much better than nothing and I used it for now. Good help for those who cant make good banners.
