During a demo at E3 2016, the Shiekah Slate had the ability to reveal an enemy's Hit Points. To do so, the players would hold the Wii U gamepad up to the screen and hold the cursor at the enemy who's Hit Points they want to see. This was removed because of how cumbersome it was and how it was almost no help in helping players on how to analyze enemy camps.
