Recently, we added the option to place pins on your home screen directly from a list of popular pins. As feedback we got that some did not add the pins, not sure what the pin would do. That is why a test button has now been added to the pin overview. With this button you can first test what the pin does. Is that what you are looking for, you can add the pin.
You can read more about adding pins to your home screen (including this update) in the manual on placing pins.
