The Implementation Tab is designed for adding items into Date Check Pro as quickly as possible.  Typically, its not used much after the initial setup, but there are use cases for this part of the program, especially when you are looking to expand the scope of what you are tracking in your store.  If you are looking to add a bulk of new items to the program, check out the article on how to use the Implementation Tab.  If not, skip this part of the program and pretend that it doesn't exist.
