This is a fun idea but I understand prioritising other stuff first since this is definitely a relatively niche thing.

But it would be cool if the loot tables could be hidden from view unless "discovered," i.e. you've explicitly rolled loot for them before. The main reason I'd be interested in this is for randomisers which use data packs to randomise loot drops -- it'd be very helpful to be able to look up things you've already discovered via breaking blocks, etc., but it would spoil everything if you otherwise could just see everything.

Fun idea! Currently EMI doesn't support recipe hiding, but once it does I would certainly consider it.
