Crafting and block update ideas for MCreator 2020.2

I would like to see furnace type if a recipe is for smelting such as another drop down menu for regular furnace, blast furnace and smoker.The next thing in the recipes is a new stonecutter option where you have an input and output slot. When creating a block, I would like to have a slab option in the block types. Also, The number 1 thing I want in this update is for it to work with minecraft 1.15.
