Setting to hide items without crafting recipe

[Bastrabun]

Can you please add a setting that hides items in the crafting guide, when they have no crafting recipe?

I believe I can remember a version where this was default, but sometime in between got changed

Relevant code in case anyone would like to work on it.

unified_inventory/api.lua

Lines 13 to 43 in afd38e0

	for name, def in pairs(minetest.registered_items) do
	if (not def.groups.not_in_creative_inventory or
	def.groups.not_in_creative_inventory == 0) and
	def.description and def.description ~= "" then
	table.insert(ui.items_list, name)
	local all_names = rev_aliases[name] or {}
	table.insert(all_names, name)
	for _, player_name in ipairs(all_names) do
	local recipes = minetest.get_all_craft_recipes(player_name)
	if recipes then
	for _, recipe in ipairs(recipes) do
	local unknowns
	for _,chk in pairs(recipe.items) do
	local groupchk = string.find(chk, "group:")
	if (not groupchk and not minetest.registered_items[chk])
	or (groupchk and not ui.get_group_item(string.gsub(chk, "group:", "")).item)
	or minetest.get_item_group(chk, "not_in_craft_guide") ~= 0 then
	unknowns = true
	end
	end
	if not unknowns then
	ui.register_craft(recipe)
	end
	end
	end
	end
	end
	end
