Okay, I added Water, Lava, Beach Sand and Desert Sand, three colours of Dirt Stairs, a single colour of Grassy Stairs (It would take forever to add a stair for every kind of grassy dirt, but I'll get there someday), I also added Crafting Becnhes of each kind of wood, and Work Tables from Terraria, of Light, Medium, dark and Birch varieties. I also added Obsidian - I'm planning to get some Cobble Obsidian in there as well, 'cuz I'm pretty sure that's what they use in Terraria.
