Rather than just the originals:
What I hope the product page can be improved to look something like this:
1) Shop name is different from owner name. Not all seller like to be called as their shop name when talking to customer. And I am sure owner would like to have different name for their store. It is clickable to go to their own product page.
2) Shop Tagline can give some customer attraction.
3) Some preview what the seller have in store would be nice.
4) I'm sure seller like to be treated special by having their own avatar.
5) Verified sign can give some confident to customer.
6) A nice visit button can make the customer to browse more of their favourite seller product.
7) No. of item selled by the seller. Will give customer confident.
8) Add shop to the favourite is a features that nice to be added.
9) Along with list of customer that favourite them. With a number.
10) Here seller will have their own name. Can create better relation with the cutomer. Clickable to see the seller info and statistic.
11) Just some seller information to give customer confident.
12) Feedback statistic at product page is a must have for any multi seller / marketplace website. This avoid scam cases as well as making the seller to be more honest with the customer in order to build their own reputation. Clickcable to see the successful trade statistic and feedback.
13) Starting date can build reputation and give customer confident.
14) This is another features that should be included in Agile PrestaShop Seller Messenger module. Rather than a public question, most of the times customer prefer a private message to ask question. For example asking prosedure to send for product replacement. Or asking for the owner phone number.
15) Clickable to open the Q/A tab.
