sneak boost and hideouts

When your sneaking, your very slow. What if you what to move fast while sneaking. If you press the sprint button while sneaking, you zoom for a 1/2 of a second. Also, you can add sneaking past mobs. (example) Zombie not looking at you? Sneak past him. And last but not least, Hideouts. Hideouts can be found by getting a special map from a mapping villiger (or what ever you call it). In these hideouts are great loot inside chest like diamonds (12% chance of spawning in a chest), netherite scrap (9.07% chance), enchanted books (mending 2.7% chance, unbreaking 7.82% chance, smite/sharpness 10.8% chance), and obsidian (16.98% chance). But, there is guards that have enchanted bows, diamond armor and diamond swords (0.0000032% chance of getting the sword when killed).
