Should add a feature that considers:

• damage protection (https://minecraft.gamepedia.com/Armor#Damage_protection)
• durability of individual items
• unbreaking enchantment
• netherite vs diamond

But it is not a big priority because I prefer seeing the slots individually anyway, like this mod

Unless I made the armor parts distinct in some way, I don't think this would actually give useful information. People who want it could consider this mod instead: https://www.curseforge.com/minecraft/mc-mods/detail-armor-bar or this https://modrinth.com/mod/updated-hud which looks like OneBar (neither are actually compatible with OneBar).
