I don't really see the chance to hit being listed is really a game breaker. Also, you can't easily estimate enemy AC. Monsters have their own natural armor class, so its a lot harder to determine their AC. Also there are class abilities, combined with dexterity, that can make it hard to realize a lightly armored character is hard to hit. A Ranger with the right Fighting Style and Medium Armor can MATCH a fighter in Plate Armor.
So "eyeballing it" doesn't really work. I think a toggle to turn it off would be fine. Besides, any time you have to make a skill check in a conversation it tells you the target you need.
