The Compact Display HUD gives you a little more information than the tradition Minecraft HUD. It eliminates the need for crafting a compass or clock, which clears two spots in your inventory. And shows you how much ammunition you have in stock.
It also displays your health and food/air meters in a more practical fashion as opposed to the meat/bubbles and hearts.
The HUD gives a more concise XP meter at the bottom and shows the armor you’re wearing. It will also display the damages for both your armor and tools/weapons. While the traditional HUD is a little more minimal, the Compact Display HUD takes up essentially the same amount of space while providing significantly more info to aid your Minecraft experience.
It would be even better if you would need to first craft the cloc’k or compas, and then it shows up in your hotbar, because this is kinda cheaty. 🙂
The armour kinda blocks the durability number.
This reminds me of the HUDs for MOBA games like LOL, DOTA, or Smite.
