If you think it's hard to keep track of your current armor durability then the ArmorDisplay mod will most likely be useful for you. A new graphical user interface for displaying each armor item will be displayed on the screen. If you switch from one armor to the other then the dynamic ArmorDisplay will change as well.
While testing we did notice some differences in terms of how the display appears on the screen based on which device is being used.
In the first image you will see how it looked on our Nexus 9 tablet and in the second image you will see how it looks on a smaller device, such as a smartphone.
