FNEI mod is more often used by ordinary players than by developers of other mods. Therefore, loading a mod with such a functional may have a bad effect on mod performance. Recently, and so complain that the mod is unstable with a large number of mods.
My suggestion:
1) The mod has debug mode, which I turn off by default (in core/debug.lua). It displays in the log any information about clicking on the mod interface. Therefore, you can click on the necessary prototypes/recipes and watch/copy them in the log.
2) You can create a fork mod and insert your output into the log or edit the mod to suit your needs as you like. I can help you figure it out.
