mini blocks and recipe papers with special recipes

*The community has numerous add-ons that offer mini-blocks, but a vanilla version would be great for more detail-oriented builders. (I'm not referring to tiny blocks that are 1 pixel high) The mini-blocks would be the size of a slab cut into 4 pieces and could be placed together to form a complete block, a vertical slab, or even more detailed decorations. *They could be made at stonecutters or the crafting table, but that would require you to have the recipe, which you can get by searching chests in structures and finding the recipe paper. This is simply a piece of paper with a recipe that, when interacted with, teaches you the recipe and allows you to craft the item. *The recipe paper adds a new mechanic where you can find special recipes by searching chests or digging with the brush. *when interacting with recipes you have already learned, you receive a small amount of xp * The recipes would also be somewhat rare so that they wouldn't be too easy to obtain, and also to give a new reason to explore all the structures.
