So if you dislike that part of the game, but still want to build huge structures and let your creativity flow, this is a perfect mod for you.
It is very helpful when you are about to build large structures, as it saves you all the time it would otherwise take to gather materials. Similar to the Too Many Items Mod, the Not Enough Items Mod (NEI) is a mod that adds an in-game inventory editor, allowing you to quickly and easily spawn items, blocks, mobs and everything else in the game, in whatever game mode you like.
