• Tag based filtering? How are tags selected. Only support tags with associated translations? (EMI!)
• Filtering by Creative Tab?
• Filtering by mod (? how are mods picked ? example item? pick from list?)
• Should deny/allowlist toggle still be done via a card? Too obtuse?
• Allow for filtering that does text-searches in item names?
• Advanced filtering like enchants?
• Block / Blockstate filtering for planes? How would selecting one or many blockstates work?

If possible, make filters as a list, like the Pipez mod.

Enchantments: I often get confused of how different mods handle this.
Would be nice to have filter options like Enchantable, Enchanted and Not enchanted.

another thing to might nice to add to check item has nbt or something similar to fuzzy card it would be a good way to handle mods that uses nbt and most non-stackable items.
