It would be useful if the shop owner could decide/set whether the link to the manufacturer's website (click on the logo/manufacturer on the product detail page) is opened externally in the new tag or in the same tab.

If a store page for the manufacturer is to be displayed instead of the manufacturer's website, this is less useful in a new tab.

Here it would be better if the owner had the option of opening the page in a new tab or in the same one
