I have an idea for setting a npcs home which is very hard to do as is maybe you could add a item that you use to right click on them to select the npc then right click the area you want them to spawn.

Clicking Set Home accomplishes this already.

But an item would make it easier to do. All I am saying is that its annoying trying to get them to stand in one certain area to set their home Or maybe you make an item so you can tell them were to stand that would also help pls think about it.
