Item Identifier is a quick little mod that allows you to identify the item id, data value, and NBT tags of the item you're holding. I made it because of the lack of the 1.8 feature of seeing item names in the tooltip in debug mode and I needed to find item names for development purposes in 1.7.10. (I know NEI does this, but does NEI give you the full NBT data of the item? (I haven't looked.))
Kind of meant for dev environments where you need item names, or for servers making kits with items, or map makers needing to give special items.
