ShulkerPeek

Hover a shulker box to see what's inside: its 27 slots appear as a 9 x 3 grid right in the tooltip, laid out exactly like the box's own screen, with item icons and stack counts.

• Works with the plain shulker box and all 16 dyed ones, whether empty, partly filled or full.
• Works on every screen with item tooltips: your inventory, chests and other containers, the creative inventory, the item panel, chat item links and trading.
• Keeps the tooltip's usual lines (name, lore, "64 x Diamond"...); the grid goes underneath.
• Respects hidden tooltips: a box whose minecraft:tooltip_display hides its contents stays hidden.
• Settings in Options > Mods > ShulkerPeek > Settings: show the grid always or only while holding Shift, show a grid for empty boxes, and tint the grid with the box's dye colour.
• Uses your resource pack's own shulker box texture.

Works in single player and on LAN worlds you host. Horizon currently leaves a box's contents out of what its built-in server sends to the game window, which is why even the "64 x Diamond" lines are missing there. ShulkerPeek sends the contents the way a vanilla server does. On vanilla servers the grid works too; on other Horizon servers without the mod, boxes look empty.

It never changes items, inventories or worlds. Turn it off any time in Options > Mods.
