The sift entry?

So like a code that generates with the seed that makes it so in random biomes/structures there is a number, and that number is a color. You you that number and it’s color to make a tune with note blocks and open the portal to the sift. So it encourages you to travel around and find things! I mean, dungeons 2 hasn’t come out yet, but I still think hink this might be a good idea.
