NEI

NEI, or Not Enough Items, is a mod made by ChickenBones that is a succesor to the popular mods TooManyItems and Recipe Book. NEI modifies the existing Inventory GUI by adding an icon list of items to the right which is searchable via a text box at the bottom of the screen. The icons, when clicked, will usually provide a recipe for how to make the item but can also provide the uses for the item (by pushing 'U' when the cursor is over the item) or provide a number of the item when cheat mode is enabled.
