Add a dedicated off-hand use button in Bedrock Edition

In Bedrock Edition, the off-hand is limited. Players must often switch items to eat, block, use a totem, or place torches, interrupting combat, mining, and survival. Proposed solution: Add a dedicated off-hand action button to use the secondary hand without opening the hotbar. It should work with food, shields, totems, torches, or weapons, allowing combat actions and survival tasks. Optional implementations to avoid clutter on mobile: Contextual button: appears only when off-hand has an item, icon matches the item. Hold-to-use: short tap → main-hand, hold → off-hand. Expandable mini-button: tap to reveal off-hand action, release to hide. Benefits: Reduces hotbar switching, improves mining and exploration, keeps Bedrock UI intact, and makes gameplay more fluid and accessible. Idea by IsNovaGG:)
