The placing blocks behind blocks (placing block without vision):

Could you add a toggle button to make sure the printer doesn't place blocks were the player cannot see ?
Could you also add a head mouvement toggle and sliders for speed of mouvements ?

player not "attacking" when placing block:

Could you add a toggle button to make the player perform the action of placing a block ?
Because the blocks are appearing in front of the player and it doesn't look like there is any interaction.
(I don't know if its also the case in multiplayer but if it is can you also make it do it)

tryng to place block that arn't in the hotbar:

The printer wants to continue placing blocks that are in the inventory and not the hotbar.
Can you make a toggle button to make sure it is not looking outside the hotbar ?

Quality of life

Can you add a toggle for blocking the oppening of the inventory when the printer is on ?
So that the printer won't place blocks while the inventory is oppened.

I might be asking for a lot but these features will greately help somme people including me.
Best regard.
