Hello,
The vendor profile in HikaMarket do list the vendor's products.
But in the HikaShop product listing, right now, the easier is to perform a view override to perform one SQL query and add the "vendor" column.
The plugin support is for my point of view, the best, but I still need some improvements to handle correctly the variants.
