First time being here and first post as well. That being said, wasn’t really sure whether or not to categorize this as an Extension or an Idea. So I went with Idea. Hope that was the right option.
Just like the Destiny and Destiny 2 armory overlay, there’s another game that I think could use this type of overlay. That game would be The Last of Us and their multiplayer mode: Factions MP. I’m sure most of you have heard about this game. 
It’s a game that I thoroughly enjoy/stream and fairly popular and would love if this could become an extension.
