What does this addon do?

Fallout 4 Style Health bar and Stamina bar is a collection of different elements that can be found in the game. It can be used as a quick reference guide to help you to remember the most important things you need to know about the game, or as a more detailed resource that will let you know about the most important things, like what weapons you can use, how much health you have, how much stamina you have, or what kind of items you can use.
