ArmorHide

/hidearmor — toggle your armor's visibility. While hidden: Other players (and your own F5 view) no longer see your armor; your head shows your player skull instead. In your inventory the four armor slots show a lime glass pane whose hover text keeps the original item's name, enchantments and durability. Unequipping reveals the real item; putting it back shows the placeholder again. The elytra stays visible (so gliding still looks right). /cosmetichat [off] — wear the item in your main hand as a cosmetic hat visible to others, while keeping your real helmet's stats. off removes it. Settings persist across reconnects and restarts in a local playerdata.yml — no database required. Command aliases: /togglearmor, /hat.
