Too lazy to organize villagers into trading hall, now you can view their trades further away by right clicking with a villager wand or advanced villager wand in the direction of a villager within 10 blocks of you. Works for all vanilla villagers.

With the normal villager wand, you can see what the trades are but not the finer details such as enchantments or potion effects for tipped arrows.
With the advanced villager wand, you can do everything the normal villager wand can do and see enchantments and potion effects by hovering over the item in the chat.
