If you try to autocraft something, AE2 shows you a window of missing item and items you have.

JEI lets you pin the items from this window directly so you don't have to remember everything and set autocraft each of them by searching their name.

EMI should be able to do this too. or atleast it would be nice to have a keybind or ingame config that'll turn off EMI and enable JEI.

currently if you disable EMI then JEI also gets disabled and the only way to use JEI is to disable EMI from the launcher or remove the mod.

this is EMI, cant pin item from here.

this is JEI, lets me pin items, useful for forgetful people like me.
