Can't remember if I've talked about this, but there needs to be a better way of tracking down villagers. Sometimes it takes what feels FOREVER just to find a villager for whatever reason. It can be very frustrating, searing almost every building and house before you find them. It's happened to me many times, and I don't even see half my villagers on most days. And this coming from someone who spends a lot of time running around everywhere in her town, so that is saying a LOT.
Sure there is the megaphone in New Leaf, and it can be very helpful, don't get me wrong, but it only works if the villager in question is outside.
I am thinking calling them on the NookPhone would be the best method.
Say, you wanna track down Ankha. Instead of having to spend Lord only knows, seaching multiple buildings and rooms to no avail, you can just call her on your NookPhone and she'll say something like "I am in the fish section of the museum."
I still think the megaphone should be available for seaching for them outside, though.
