GigiHello Kitty Island Adventure tip, if you display the daily item you get from residents in their house, you don't have to try and remember who gives what.
It's not necessary early game, but after you get a lot a visitors as permanent residents it's easy to forget what they give you.
(For context, I don't gather from them every day and I've not been playing for a year yet, so not even close to getting Milk)
