You know how animals, trees, plants, etc. all glow when you walk by them to let you know that you can interact with them?
Well, where there's several things you can interact with and you press enter, they all stop glowing. I propose that, as you scroll through your options (say, three pigs and a chicken), the animal currently highlighted along the bar of animals (or whatever you're interacting with) gets its glow back!
This would help with those times when there's several piggies, and you're trying to make sure you nibble or pet each one, but you lose track of their names. I find it easier to watch the animals to keep track of who has been nibbled and who hasn't.
