Hello!

I would like to suggest that you use the tag forge:chests/wooden as the chest ingredient in your recipes, so things like Ender Chests and Mekanism Personal Chests aren't valid options. Seeing JEI cycle through very different blocks is a bit misleading, imo.
This is just a personal preference of course, feel free to reject it :)

Thanks. The data pack system is still a thing I'm adjusting to along with all the nuances of categorization.
