Ideas For A Minecraft Map?

Me and a group of friends have built a Minecraft map using triggers.
So far, we have:

A working hunger system
Crafting recipes
The nether
Advancements
Farming
Mines
Smelting Recipes

(btw, we don’t have season ticket)
Do you have an idea for how to make a furnace that can be accessed through a game overlay? I just used a pop-up with call to actions, however we cant use lists so there is a maximum of two recipes, any ideas to bypass this limitation?

Make it so that the first button is a recipe, and the second button is a next button to send you to another recipe, and you do that over and over again.

add the end and the ender dragon or add villages with villages you can tarde with

_Meow is asking for a way to create a furnace in GKC, not ideas for his Minecraft map.
