We should have the option to see hands, feet and weapons while in first-person camera mode. Currently, first-person mode does nothing to make you feel like you are one with your character. Like in FPS games where you can see your gun in front of you, we should be able to see ourselves fighting. Such an implementation would also help to gauge distance while in first-person mode. At present, we have no point of reference for our bodies relative to our targets, thus we cannot appropriately position ourselves in the heat of battle without lots of practice. There is very little incentive to play in this mode, while it could be the most immersive way to experience Eberron. Peripheral vision would also be something worth considering (maybe even with multiple monitor support, but that's a bit more difficult to pull off). What do you guys think? Is this something you want to see developed?
EDIT: If this were to be implemented we could have some sort of warning system that would alert us if something was attacking from off camera. This way we would know which way to turn during an intense fight.
