The control for this has been moved to the following admin tool:

LISTING SETUP > FIELDS TO USE

That admin tool will allow you to control the display of the storefront link site wide. The field to use support wiki page explains that admin tool in more detail. The fields to use admin tool allows you to control the display of the storefront link just like you do for other columns/fields in the software site wide. You can then use category specific field configurations to control that on a category by category level. The category specific field configuration wiki page will describe how to do that.
