I was wondering if it is possible to add an option next to the flashlight settings and the others to be able to disable and enable the player's name to be displayed at the top of it, since it is usually annoying in singleplayer and to take photos. In addition, this could improve performance in multiplayer, since it would be one less entity (the armor stand) to teleport for each player.

Sorry for my bad english.

I was just working on the options, so why not?
It won't improve performance though, as that entity is the "source" entity of the whole player model, it all teleports relative to it. (It is a necessary entity, due to how the player rotating works.)
