This sounds a bit specific but I'd like to see the dog tags/holo tags and the locket junk items in the base fallout 4 game to be wearable as they are items which quite a characters (BoS members with holo tags) and niche side quests (Annikas locket quest) contain but have no value and making them a wearable item might give the player a tiny bit more incentive to not just throw them away. Plus the wedding ring is the only 'jewellery' item in the base game so it would be nice to see the selection slightly varied.
