When removing duplicate items such as ingots, I keep the tag for the type of ingot they are, (e.g. forge:ingots/lead etc) just in case a player happens to come across this version of the item due to an oversight on my part for some reason. However this means in the recipe viewer, most of the time the item that actually gets displayed as the 'default' item is one that is unobtainable, and not the one I'd prefer. I could easily fix this by removing the offending item from the tag but I'd prefer not to.

This is a totally QOL change and doesn't impact the gameplay at all but I would really like a way to prioritise certain items so that they are the ones displayed to represent the tag rather than another. This could be a list of 'priority items' in the config that are always chosen first if they exist in a tag, listed in order of importance (in case multiple items are in the same tag). This way the item you first see in the recipe is always going to be the one you actually use, to avoid confusion. For example, with lead ingots I would just put ['oreganized:lead_ingot'] in this list and then it will become the highest priority item in all of the tags it exists in, so any recipe that uses a tag it's in will display that specific item.

The wiki has a few pages on this, you have a few routes for this. For one, you can "disable" all lead ingots you don't use, it'll remove them from tags and make navigating the recipes easier. You can also model the tag and use whatever ingot textures you want.
