Hi,
The best will be to use an hidden category (a category which is not published) that you can called "featured".
The module will make a listing from this category and because the category is unpublished, it won't be displayed in the rest of the website.
After that, you can manage the feature products by adding or removing them from the category (because a product can have several categories, it does not affect the rest of the website).
