The configurable tooltips is currently the only implemented feature of the original mod. JEI Integration is still in the development phase meaning some features of the original mod are not present.
In addition to additional recipe handlers, it adds configurable tooltips which can provide insightful information for pack developers and tech-savvy players. The mod provides JEI recipe handlers for other mods where otherwise absent. JEI Integration, the successor to NEI Integration by Tonius, is an addon for Just Enough Items (JEI) for Minecraft 1.10 and above.
