Make some visual changes to the smithing table！

I am assuming are asking if I could make items stay inside the smithing interface similar to a chest and also change the texture of the block in game.
Sadly, to make the items stay inside the smihting interface after closing it requires making changes to server side code, which is not possible in a client only mod. Also, I don't want to bundle a new texture for the smiting table with the mod because many people would probably not want that. If you want a custom texture, I recommend installing a resource pack on top of the mod.
