I think it would be cool if instead of choosing to toggle entity names or all names, you could choose to toggle player names while keeping entity names on.
I also think it would be cool to add an option to make player names render like entity names where they only appear when you're looking at the player, but since there are other mods that show you what a players username is when you look at them (usually made for servers that have player names toggled off), it's not a priority.
