Now in my opinion, only 4 things remain to make this plugin absolutely perfect:
- Limit cart to be able to process orders only with products from same seller
- Add shipping options
- eCommerce orders search, using the Order ID, Customer Email and Customer Name
- Products Management - Search, using the item ID, Item Title, On sale, Quantity, Shipping fee and Status (this search will help if a store has lots of products and you need to quickly find one and make modifications)
This will help us a lot in creating a hybrid system - classifieds and eCommerce (selling our products) and also will bring eCommerce to Osclass (you can even create themes just for eCommerce! 
).
Thanks!
Wow, I would also like to see this.
I have an auto parts physical shop and I would like to make an auto classifieds site, where I could also sell my shop's products.
