After looking through nei and having played quite a bit in single player I believe that more items from twilight forest should be craft able because they are loads of fun. for example the knightmetal ingots ( because this would allow loads more items to be crafted), the peacock feather fan, the various swords and bows( except possibly the ender bow I know that’s caused crashes in the past), the other armour sets,the cube of annihilation which is absolutely awesome but may cause grief protection problems might work if you make it work like wands,naga scales , and definitely experiment 115 cause who doesn’t want cherry pie?
