Jei Integrations
Mods that add items or blocks which give a random reward for the player now include their own JEI category. Some mods that include this integration are: Dungeon Tactics, Extra Botany, Thaumcraft
(Dungeon Tactics also requires Just Enough Resources to show the bag loot)
Alchemical Cauldron previously required you to read through the Dungeonpedia books to learn what you can do with them. Not anymore!
Several items and blocks include information tab entries with, for example, instructions to obtaining or using them.
