CookieList is a generic addon that can be used for keeping wishlists, user favorites and other similar content. It allows you to define the value that needs to be saved which means it is not restricted to Resources, but may also be used to provide wishlist functionality for custom components. As the name indicates, it stores data in a Cookie.
Install the package and head over to the documentation for usage instructions.
