Changing the marketplace, so product open in new window

Hi,

Im was thinking about how to make it possible, when users browsing the marketplace, then when they click a product and get redirected to subsite, could this happens in a new window maybe? So they still have the marketplace open in a window.

Else if there is another way to sent the user back to the marketplace (main site) after they have been on a subsite for looking a products, then im listening.

Best regards,
