With all of the items that were considered to be either trash or items to be used for crafting, it'd actually be cool for the characters to actually use in terms of an action emote. Such as playing a harmonica or guitar, tossing a baseball in the air (or juggling bunch of them, or even pool/billard balls).
Heck, even being able to throw baseballs and otherwise non-combat items, even if it's knock-out damage, would be nice.
This would expand the number of objects that can be interacted with, and could be used to supplement side quests (such as trying to distract NPCs or even entertain them, like going up on stage and playing for the audience, etc.).
To use these items, they would probably have to be equipped to enable this, which is understandable.
I've seen emotes on Steam and other mod sites, but it would be nice if there were official ones (that didn't cause bugs or other problems in the game).
