Today I spent a bit of time petting and subsequently nibbling a lot of piggies. When two piggies were very close together, it was nigh impossible to tell which piggy I was interacting with at a given time. Normally, who cares, but if there's a penalty for nibbling a given piggy too often, I'd like to be able to avoid it.
Maybe when we hover over or cursor down to an object's name in the "interact with" list, the object could get a fuzzy highlight (aura?) around it to indicate which of that object I'm interacting with.
